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 = 4b + 7y - 9 for b in terms of y.
| \(\frac{2}{3}\)y + \(\frac{1}{3}\) | |
| -\(\frac{2}{3}\)y + \(\frac{2}{3}\) | |
| 1\(\frac{1}{4}\)y + \(\frac{3}{4}\) | |
| -8y + 9 |
