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 -5b + b = -7b - 2y + 5 for b in terms of y.
| -8y - 4 | |
| -1\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| \(\frac{3}{4}\)y + \(\frac{1}{4}\) | |
| \(\frac{5}{12}\)y + \(\frac{3}{4}\) |
