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 c - 2c = 6c + 9x - 8 for c in terms of x.
| -\(\frac{8}{13}\)x + \(\frac{2}{13}\) | |
| \(\frac{2}{5}\)x + \(\frac{9}{10}\) | |
| -\(\frac{6}{11}\)x + \(\frac{6}{11}\) | |
| -2\(\frac{1}{5}\)x + 1\(\frac{3}{5}\) |
