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 -2c + 7c = -7c + 2x - 6 for c in terms of x.
| -x - 1\(\frac{1}{5}\) | |
| 1\(\frac{1}{2}\)x - \(\frac{2}{5}\) | |
| \(\frac{1}{17}\)x + \(\frac{3}{17}\) | |
| x - 2 |
