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 - 3b = 2b + 2y - 8 for b in terms of y.
| -2y + 3 | |
| y - 3 | |
| -\(\frac{5}{11}\)y + \(\frac{8}{11}\) | |
| y + \(\frac{1}{12}\) |
