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