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 a - 5a = -5a - 7x + 9 for a in terms of x.
| 2\(\frac{1}{2}\)x - 3 | |
| -\(\frac{5}{13}\)x + \(\frac{2}{13}\) | |
| -\(\frac{1}{3}\)x + 1\(\frac{1}{2}\) | |
| -3x + 3 |
