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 - 4a = -2a - 3x - 9 for a in terms of x.
| -\(\frac{1}{4}\)x + 2\(\frac{1}{4}\) | |
| -\(\frac{1}{5}\)x - \(\frac{3}{10}\) | |
| x + \(\frac{4}{5}\) | |
| 2\(\frac{1}{2}\)x - 1 |
