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