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 + 9a = -6a - 2y - 2 for a in terms of y.
| -2\(\frac{1}{3}\)y - 1 | |
| \(\frac{1}{13}\)y - \(\frac{8}{13}\) | |
| 5y + 2\(\frac{2}{3}\) | |
| -1\(\frac{3}{8}\)y - \(\frac{1}{4}\) |
