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 + 6c = 9c + 9x + 2 for c in terms of x.
| -\(\frac{3}{10}\)x - \(\frac{1}{5}\) | |
| -\(\frac{9}{11}\)x + \(\frac{7}{11}\) | |
| -2\(\frac{1}{3}\)x - 1\(\frac{1}{6}\) | |
| x - 1\(\frac{1}{2}\) |
