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