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