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 -3a - 6a = 8a - 3y - 2 for a in terms of y.
| -2y + 1 | |
| -\(\frac{3}{11}\)y + \(\frac{2}{11}\) | |
| \(\frac{1}{11}\)y + \(\frac{2}{11}\) | |
| y + \(\frac{5}{9}\) |
