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 - 7c = c + 4x - 4 for c in terms of x.
| -\(\frac{5}{6}\)x - \(\frac{7}{12}\) | |
| -1\(\frac{4}{7}\)x + \(\frac{2}{7}\) | |
| -\(\frac{5}{7}\)x - \(\frac{1}{7}\) | |
| -2\(\frac{3}{4}\)x + 1 |
