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 4a - 4a = -9a + 8x - 8 for a in terms of x.
| \(\frac{2}{3}\)x - 3 | |
| -\(\frac{6}{13}\)x - \(\frac{7}{13}\) | |
| \(\frac{12}{13}\)x - \(\frac{8}{13}\) | |
| -1\(\frac{4}{9}\)x - 1 |
