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