When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 7a - 3a = 4a - 2x - 2 for a in terms of x.
| 3x + 7 | |
| \(\frac{11}{14}\)x - \(\frac{9}{14}\) | |
| -2x + 1 | |
| \(\frac{1}{3}\)x - \(\frac{2}{3}\) |
