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 = -6c - 3x - 6 for c in terms of x.
| -\(\frac{5}{6}\)x - \(\frac{1}{6}\) | |
| -\(\frac{7}{8}\)x + \(\frac{1}{4}\) | |
| 3x - 7 | |
| 1\(\frac{1}{3}\)x - 2 |
