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 5a + 6a = -5a - 9y - 8 for a in terms of y.
| -1\(\frac{1}{2}\)y - \(\frac{4}{5}\) | |
| -\(\frac{4}{15}\)y - \(\frac{4}{15}\) | |
| -\(\frac{1}{6}\)y + 1\(\frac{1}{6}\) | |
| \(\frac{3}{7}\)y + \(\frac{3}{7}\) |
