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 - 9c = -9c - x + 4 for c in terms of x.
| \(\frac{11}{13}\)x + \(\frac{8}{13}\) | |
| 1\(\frac{1}{3}\)x + \(\frac{2}{3}\) | |
| 3\(\frac{2}{3}\)x + 3 | |
| -\(\frac{7}{9}\)x + \(\frac{5}{9}\) |
