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 3b + 7b = -5b - 8y - 7 for b in terms of y.
| -\(\frac{1}{4}\)y - \(\frac{1}{12}\) | |
| -1\(\frac{7}{8}\)y - \(\frac{7}{8}\) | |
| 1\(\frac{2}{11}\)y - \(\frac{2}{11}\) | |
| -y - 3\(\frac{1}{2}\) |
