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