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