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