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 8a - 8a = -a - 2x - 9 for a in terms of x.
| \(\frac{2}{3}\)x - 1 | |
| x + 6 | |
| -x + 1 | |
| 1\(\frac{4}{9}\)x - \(\frac{2}{9}\) |
