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