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 -a - 2a = -5a - x + 8 for a in terms of x.
| \(\frac{1}{4}\)x + 2 | |
| -5x - 1\(\frac{1}{3}\) | |
| \(\frac{1}{13}\)x - \(\frac{6}{13}\) | |
| -3\(\frac{1}{4}\)x + 1\(\frac{3}{4}\) |
