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