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 -8a + 4a = -2a - 5y + 5 for a in terms of y.
| -3\(\frac{1}{2}\)y + 2 | |
| \(\frac{3}{5}\)y + \(\frac{2}{5}\) | |
| -\(\frac{1}{2}\)y - 3 | |
| 1\(\frac{1}{2}\)y - \(\frac{5}{6}\) |
