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