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 = 5b - 7y - 8 for b in terms of y.
| -y - 2 | |
| -\(\frac{7}{12}\)y - \(\frac{3}{4}\) | |
| -3\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) | |
| -\(\frac{7}{9}\)y + \(\frac{5}{9}\) |
