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 - 6a = 3a + 9y - 7 for a in terms of y.
| -2\(\frac{1}{7}\)y + 1 | |
| -\(\frac{10}{17}\)y - \(\frac{2}{17}\) | |
| \(\frac{4}{7}\)y - \(\frac{1}{14}\) | |
| 2\(\frac{3}{4}\)y + 2 |
