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 4c - 9c = 5c + 8x - 6 for c in terms of x.
| -17x + 6 | |
| 3x - 2\(\frac{1}{2}\) | |
| -\(\frac{11}{12}\)x - \(\frac{7}{12}\) | |
| \(\frac{1}{10}\)x + \(\frac{3}{5}\) |
