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 -3a - 8a = 8a + 5y - 8 for a in terms of y.
| -\(\frac{1}{11}\)y - \(\frac{6}{11}\) | |
| -y - \(\frac{3}{4}\) | |
| -\(\frac{2}{5}\)y + \(\frac{7}{10}\) | |
| -1\(\frac{2}{11}\)y + \(\frac{8}{11}\) |
