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 + 2a = 7a + 2y + 2 for a in terms of y.
| y - \(\frac{7}{12}\) | |
| 7\(\frac{1}{2}\)y - 2 | |
| y - \(\frac{1}{4}\) | |
| -\(\frac{3}{5}\)y - \(\frac{2}{5}\) |
