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 - 9a = -3a - 6y - 8 for a in terms of y.
| \(\frac{8}{11}\)y - \(\frac{7}{11}\) | |
| -1\(\frac{1}{2}\)y + 4 | |
| \(\frac{8}{15}\)y + \(\frac{4}{15}\) | |
| 5\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) |
