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 + 5b = -b + 9y + 7 for b in terms of y.
| \(\frac{1}{2}\)y + \(\frac{7}{8}\) | |
| 2y - \(\frac{3}{7}\) | |
| -2y - \(\frac{1}{2}\) | |
| -3y - \(\frac{1}{4}\) |
