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