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 - 9y - 1 for b in terms of y.
| y + 1 | |
| \(\frac{3}{16}\)y + \(\frac{1}{8}\) | |
| 2\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) | |
| \(\frac{1}{14}\)y - \(\frac{5}{14}\) |
