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 + 8b = -9b + 9x - 7 for b in terms of x.
| x - 7 | |
| -\(\frac{5}{12}\)x - \(\frac{1}{2}\) | |
| x + \(\frac{1}{4}\) | |
| x + 5 |
