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