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 -7b - 8b = -8b - 7y - 4 for b in terms of y.
| -5y + 4 | |
| -y + 1 | |
| y - 4 | |
| -1\(\frac{4}{13}\)y - \(\frac{2}{13}\) |
