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