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 - 6c = -c - 4x - 7 for c in terms of x.
| -\(\frac{1}{3}\)x + 1\(\frac{1}{6}\) | |
| -\(\frac{1}{13}\)x - \(\frac{5}{13}\) | |
| 1\(\frac{1}{6}\)x + \(\frac{1}{2}\) | |
| \(\frac{1}{4}\)x + \(\frac{1}{16}\) |
