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 -3a - 7a = 3a - 8x - 6 for a in terms of x.
| -1\(\frac{1}{2}\)x - 1 | |
| -\(\frac{1}{2}\)x + \(\frac{1}{4}\) | |
| \(\frac{2}{3}\)x - \(\frac{1}{3}\) | |
| \(\frac{1}{6}\)x + 1 |
