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 -3c + c = 9c + 9x + 7 for c in terms of x.
| -\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| \(\frac{4}{5}\)x - \(\frac{7}{10}\) | |
| x + \(\frac{5}{11}\) | |
| -\(\frac{2}{3}\)x - \(\frac{7}{12}\) |
