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