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 5c - c = c + 7x + 2 for c in terms of x.
| -\(\frac{7}{10}\)x - \(\frac{2}{5}\) | |
| 2x + 7 | |
| 2x + \(\frac{1}{2}\) | |
| -\(\frac{4}{13}\)x - \(\frac{8}{13}\) |
