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 = -8c + 4x + 6 for c in terms of x.
| -x + \(\frac{3}{10}\) | |
| -\(\frac{10}{13}\)x + \(\frac{1}{13}\) | |
| \(\frac{1}{2}\)x - \(\frac{3}{4}\) | |
| -\(\frac{1}{17}\)x + \(\frac{6}{17}\) |
