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