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 4c + 7c = -c + 8x - 4 for c in terms of x.
| \(\frac{5}{6}\)x + \(\frac{1}{2}\) | |
| -x - 2\(\frac{1}{4}\) | |
| \(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| 1\(\frac{7}{8}\)x + 1 |
