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