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 2a - 7a = 4a - 4x - 8 for a in terms of x.
| -\(\frac{1}{6}\)x + \(\frac{2}{3}\) | |
| -x - \(\frac{4}{13}\) | |
| -3\(\frac{2}{5}\)x + 1 | |
| -1\(\frac{1}{2}\)x + 4 |
