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 -9c + 8c = -4c - 5x + 5 for c in terms of x.
| -\(\frac{3}{5}\)x - \(\frac{4}{5}\) | |
| 2\(\frac{3}{5}\)x - 1 | |
| -\(\frac{2}{7}\)x - \(\frac{1}{7}\) | |
| -\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) |
