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 5a + 2a = -8a - x + 2 for a in terms of x.
| -1\(\frac{4}{5}\)x - 1\(\frac{2}{5}\) | |
| x - \(\frac{1}{12}\) | |
| -\(\frac{3}{13}\)x + \(\frac{2}{13}\) | |
| -x + \(\frac{4}{13}\) |
