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 + 8b = -b + 7y + 2 for b in terms of y.
| 2\(\frac{1}{2}\)y + 2 | |
| \(\frac{1}{4}\)y - 1\(\frac{1}{8}\) | |
| -\(\frac{5}{13}\)y + \(\frac{5}{13}\) | |
| \(\frac{1}{4}\)y - \(\frac{1}{2}\) |
