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 -6c + 9c = 7c - 5x - 8 for c in terms of x.
| 3x - 1 | |
| x + 1\(\frac{3}{5}\) | |
| 1\(\frac{1}{13}\)x + \(\frac{8}{13}\) | |
| 6\(\frac{1}{2}\)x - 4 |
