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 -8b + b = 7b + 7y + 7 for b in terms of y.
| -\(\frac{1}{8}\)y + \(\frac{3}{8}\) | |
| -y + 2 | |
| -\(\frac{2}{5}\)y - \(\frac{7}{15}\) | |
| 4y - 4 |
