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 - 8a = -7a - 5x + 7 for a in terms of x.
| -3x - 7 | |
| \(\frac{1}{3}\)x - \(\frac{1}{2}\) | |
| -2\(\frac{3}{4}\)x + 1\(\frac{3}{4}\) | |
| \(\frac{2}{11}\)x - \(\frac{2}{11}\) |
