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 + 2c = -8c + x - 9 for c in terms of x.
| \(\frac{6}{7}\)x + \(\frac{1}{7}\) | |
| \(\frac{3}{10}\)x - \(\frac{1}{10}\) | |
| -\(\frac{1}{2}\)x - 4\(\frac{1}{2}\) | |
| -1\(\frac{1}{5}\)x - \(\frac{2}{5}\) |
