Term | Definition |
---|---|
Constant | A term without a variable Ex. 5 |
Variable | A symbol used to represent a quantity that can change Ex. x |
Coefficient | number in front of a variable (multiplied) |
Like Terms | Terms that contain the same variables raised to the same power. |
Distributive Property | a(b + c) = ab + ac |
Solve 1-step Equation | Do the opposite operation |
Opposite Operation of Addition | subtraction |
Opposite Operation of Subtraction | addition |
Opposite Operation of Multiplication | division |
Opposite Operation of Division | Multiplication |
Solve a 2-step equation (get x by itself) | Use the oppostie operation to 1. Add or subtract the CONSTANT (NUMBER) on the same side as the variable 2. Multiply or divide the COEFFICIENT (NUMBER IN FRONT OF VARIABLE) |
solve multi step equations | 1. Distribute- same side 2. Like Terms- same side 3. add or subtract constant- different sides 4. multiply or divide coeffient- different sides |
