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 7a + 5a = -7a - 6y - 2 for a in terms of y.
| \(\frac{1}{13}\)y - \(\frac{9}{13}\) | |
| \(\frac{1}{2}\)y + \(\frac{1}{2}\) | |
| -\(\frac{1}{2}\)y + 4\(\frac{1}{2}\) | |
| -\(\frac{11}{14}\)y - \(\frac{1}{7}\) |
