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 4b + 5b = -8b + 4y + 7 for b in terms of y.
| -1\(\frac{4}{9}\)y - \(\frac{5}{9}\) | |
| \(\frac{7}{12}\)y + \(\frac{7}{12}\) | |
| -\(\frac{1}{12}\)y + \(\frac{7}{12}\) | |
| 17y + 5 |
