Key Learning Points from Solving Linear Equations

In your opinion, write down ALL the key learning points from solving linear equations.

eg. what to look out for? what's the basic understanding?

  2. 1) LHS=RHS
    2) What you do on the left must be done on the right and vice versa
    3) Algebraic rules still/may apply

  3. Do the same thing on both side. If you minus 2 n one side, minus 2 on the other side.
    Look out for negative and positive. If u minus -2 on one side, +2 on the other side.
    If you divide something one number not in bracket, you have to divide the other numbers(except for numbers that is in brackets)

  4. make sure both sides are equal
    make sure you apply the working to both sides
    always make sure the unknown is a positive

  5. - A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable.
    - Linear equations can have one or more variables.
    - Linear equations occur abundantly in most subareas of mathematics and especially in applied mathematics.

  6. We should balance both terms, and each line should consist of the variable.

  8. Look out for (positive and negative) signs to know whether to add or subtract and make sure that what you do on one side must be equal on the other side to find out the unknown.

  9. 1. LHS and RHS must be equal
    2. Linear equations can have one or more variables
    3. Negative and positive CAN trick you. If you minus 2 off of one side, you must add 2 to the other side.

  10. -Both sides must always be equal
    -When making changes to one side, the other also must be changed by the same way as the first

  11. Always remember that both sides of the equation must always be equal all the time.

  12. Whatever affects one side the other side will also be affected.
    Linear equations can have more than one variable
    Make sure the variation / unknown value is a POSITIVE

  13. When solving linear equations, we must make sure that RHS and LHS remain the same and not change the values.

  14. There must be balance
    Algebric methods and rules still apply to the equation.

  15. 1. LHS must be equal to the RHS
    2. Algebraic rules will still apply
    3. Whatever changes you make on either side must be made on the other side

  16. - All sides are equal
    - Put algebra variables on one side and the whole numbers alone on another side.
    - The operation on the left of the number or the algebra variable tells the solver that they should either + or - to make both sides equal.

  17. 1)Left hand side = Right hand side. ALWAYS.
    2) Remove brackets when you can.
    3) If it is like -(5-x) , there is an invisible one. -1(5-x)
    4) ( ͡° ͜ʖ ͡°)xXLennyClanXx( ͡° ͜ʖ ͡°)

  18. LHS=RHS
    Do the LFS first then the RHS
    When the algebra is negative on the LHS, put a plus minus sign on the RHS

  19. 1. Remember to check the operations in math
    2. make sure both sides have a different variable
    3. always expand first

  20. 1. LHS=RHS
    2. If the number on the left is negative, add it to the right instead of subtracting
    3.everything must be balanced

  21. Do the same thing to both sides of the equation.
    Both sides must be equal (LSH=RHS)

  22. A Linear Equation is a statement that has two expression that is equal and in which the highest variable is unknown

  23. In Linear Equations, the number on the Left-hand-side must be equal to the number on the Right-hand-side, and any changes made to one side must also be made to the other side to ensure equal values on each side.
