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 7b - 5b = -9b + 9y + 2 for b in terms of y.
| 2\(\frac{1}{5}\)y - \(\frac{1}{5}\) | |
| \(\frac{7}{8}\)y + \(\frac{1}{8}\) | |
| \(\frac{1}{2}\)y - 2\(\frac{1}{2}\) | |
| -1\(\frac{1}{3}\)y + \(\frac{1}{2}\) |
