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 -4a + 4a = 9a - 3y - 8 for a in terms of y.
| 4\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| \(\frac{3}{11}\)y + \(\frac{5}{11}\) | |
| 1\(\frac{1}{6}\)y + \(\frac{1}{6}\) | |
| \(\frac{7}{13}\)y + \(\frac{8}{13}\) |
