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 -2a - a = -4a + 6y + 6 for a in terms of y.
| -1\(\frac{1}{14}\)y + \(\frac{3}{14}\) | |
| -\(\frac{1}{2}\)y - 3 | |
| -\(\frac{4}{5}\)y + \(\frac{2}{5}\) | |
| 3\(\frac{1}{2}\)y + 3 |
