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 6a - 9a = 5a - x - 5 for a in terms of x.
| 8x - 5 | |
| -1\(\frac{3}{8}\)x - 1\(\frac{1}{8}\) | |
| \(\frac{3}{14}\)x - \(\frac{1}{14}\) | |
| -5x + 3 |
