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 -7a + 4a = -4a - y + 4 for a in terms of y.
| 1\(\frac{2}{3}\)y - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
| 2\(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
| -y - \(\frac{3}{14}\) |
