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