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 -9b - 2b = 7b - 8x + 2 for b in terms of x.
| 8x + 6 | |
| -\(\frac{1}{13}\)x - \(\frac{5}{13}\) | |
| \(\frac{3}{8}\)x - \(\frac{1}{8}\) | |
| x + 2 |
