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 9a - 5a = -5a - 8x + 3 for a in terms of x.
| -2x - 1 | |
| 1\(\frac{3}{5}\)x + \(\frac{4}{5}\) | |
| -\(\frac{3}{14}\)x + \(\frac{3}{14}\) | |
| 2\(\frac{1}{2}\)x + 1 |
