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 - 5x - 4 for a in terms of x.
| -\(\frac{1}{9}\)x + \(\frac{8}{9}\) | |
| \(\frac{1}{3}\)x - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| \(\frac{5}{6}\)x + 1\(\frac{1}{3}\) |
