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 -9c + 4c = 8c + 4x - 4 for c in terms of x.
| x + \(\frac{4}{17}\) | |
| \(\frac{1}{5}\)x + 1\(\frac{2}{5}\) | |
| x - \(\frac{5}{9}\) | |
| \(\frac{1}{7}\)x + \(\frac{5}{14}\) |
