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 - 3a = 2a - y - 2 for a in terms of y.
| 1\(\frac{1}{5}\)y - \(\frac{1}{2}\) | |
| -\(\frac{1}{8}\)y - \(\frac{1}{2}\) | |
| -\(\frac{2}{5}\)y + \(\frac{2}{5}\) | |
| -3\(\frac{1}{4}\)y + \(\frac{1}{4}\) |
