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 8b + 9b = 7b - x - 8 for b in terms of x.
| -10x - 8 | |
| -3x - 8 | |
| -\(\frac{1}{4}\)x + \(\frac{1}{4}\) | |
| x - \(\frac{1}{10}\) |
