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 2b - b = b - 9y + 3 for b in terms of y.
| 1\(\frac{4}{5}\)y - 1\(\frac{4}{5}\) | |
| \(\frac{1}{3}\)y + \(\frac{1}{3}\) | |
| y - 2 | |
| -8y + 3 |
