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 = -5a - 9y - 6 for a in terms of y.
| 2\(\frac{5}{6}\)y + \(\frac{2}{3}\) | |
| \(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
| -13y - 6 | |
| -\(\frac{3}{5}\)y + 1 |
