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