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 - 6a = 6a + 3y - 2 for a in terms of y.
| -3y - 7 | |
| 1\(\frac{3}{5}\)y + \(\frac{1}{5}\) | |
| -\(\frac{11}{12}\)y + \(\frac{2}{3}\) | |
| -9y + 2 |
