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 6a - 2a = 4a - 8y - 2 for a in terms of y.
| 6y + 4 | |
| -y - \(\frac{1}{3}\) | |
| y - \(\frac{2}{3}\) | |
| -3y - 1 |
