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 + 5c = 6c + 9x + 7 for c in terms of x.
| \(\frac{14}{17}\)x - \(\frac{4}{17}\) | |
| -\(\frac{4}{15}\)x - \(\frac{7}{15}\) | |
| \(\frac{12}{13}\)x + \(\frac{4}{13}\) | |
| -11x + 9 |
