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 9c - 4c = 3c + 5y + 9 for c in terms of y.
| 1\(\frac{3}{13}\)y - \(\frac{7}{13}\) | |
| 1\(\frac{2}{15}\)y - \(\frac{2}{5}\) | |
| -1\(\frac{1}{2}\)y + \(\frac{3}{8}\) | |
| 1\(\frac{1}{2}\)y + 1\(\frac{1}{2}\) |
