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