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