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 = 3c + 7x - 6 for c in terms of x.
| 4x - 4 | |
| -\(\frac{4}{13}\)x + \(\frac{5}{13}\) | |
| -8x + 1 | |
| -\(\frac{1}{12}\)x + \(\frac{1}{2}\) |
