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