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 + 4b = -7b + 9y + 5 for b in terms of y.
| 6y - 4\(\frac{1}{2}\) | |
| \(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| 1\(\frac{1}{4}\)y + 1 | |
| 5y + 9 |
