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