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 + 6b = 5b + 3y - 5 for b in terms of y.
| y - 4\(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| \(\frac{9}{13}\)y + \(\frac{4}{13}\) | |
| -y + 7 |
