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 + 6 for b in terms of y.
| y - 6 | |
| -\(\frac{2}{5}\)y - \(\frac{1}{2}\) | |
| \(\frac{1}{9}\)y - \(\frac{1}{3}\) | |
| -\(\frac{2}{3}\)y - \(\frac{7}{12}\) |
