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 4c + 2c = -8c + 9y - 9 for c in terms of y.
| \(\frac{14}{15}\)y - \(\frac{1}{5}\) | |
| -\(\frac{4}{7}\)y + \(\frac{3}{7}\) | |
| \(\frac{7}{12}\)y - \(\frac{3}{4}\) | |
| \(\frac{3}{4}\)y - \(\frac{1}{16}\) |
