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 + 9b = 4b + 4y - 2 for b in terms of y.
| -y - \(\frac{2}{5}\) | |
| 2y - 1 | |
| -\(\frac{11}{17}\)y + \(\frac{2}{17}\) | |
| -\(\frac{1}{4}\)y + \(\frac{1}{2}\) |
