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