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 + 7a = -9a - y + 6 for a in terms of y.
| \(\frac{2}{13}\)y + \(\frac{1}{13}\) | |
| -\(\frac{2}{5}\)y - 1\(\frac{2}{5}\) | |
| \(\frac{5}{12}\)y + \(\frac{1}{4}\) | |
| -\(\frac{8}{11}\)y + \(\frac{6}{11}\) |
