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