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 - a = -8a - 5x - 2 for a in terms of x.
| x - 1\(\frac{1}{3}\) | |
| 1\(\frac{1}{4}\)x + \(\frac{1}{8}\) | |
| -7x - 6 | |
| 4x + 2 |
