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 - a = 3a + 7y - 6 for a in terms of y.
| 2\(\frac{2}{3}\)y - 2 | |
| 1\(\frac{2}{3}\)y - \(\frac{2}{3}\) | |
| 5\(\frac{1}{2}\)y + 3 | |
| 9y + 4 |
