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