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