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 - 9c = -8c + 7x + 7 for c in terms of x.
| -5x - 4 | |
| 16x + 7 | |
| -\(\frac{2}{7}\)x - \(\frac{3}{14}\) | |
| -4x + 8 |
