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 6a + 8a = -7a - 3y - 9 for a in terms of y.
| \(\frac{3}{14}\)y - \(\frac{1}{14}\) | |
| \(\frac{2}{9}\)y - \(\frac{2}{3}\) | |
| -\(\frac{11}{13}\)y - \(\frac{9}{13}\) | |
| 4y - 1\(\frac{1}{3}\) |
