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 4a - 4a = 6a + 2y - 4 for a in terms of y.
| -\(\frac{1}{7}\)y + \(\frac{1}{14}\) | |
| -\(\frac{1}{3}\)y + \(\frac{1}{6}\) | |
| 2\(\frac{2}{3}\)y - 2\(\frac{1}{3}\) | |
| -3y + 2 |
