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