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 + 3b = 2b + 8y + 7 for b in terms of y.
| 5y + 7 | |
| 4\(\frac{1}{2}\)y + 3\(\frac{1}{2}\) | |
| 6y + 9 | |
| 5y + 5 |
