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 2b + 9b = b - 8y + 8 for b in terms of y.
| -17y + 8 | |
| \(\frac{2}{5}\)y - 1\(\frac{4}{5}\) | |
| y - 1\(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\)y - 1\(\frac{1}{6}\) |
