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 2c - 3c = 9c + x - 8 for c in terms of x.
| -\(\frac{4}{7}\)x + 1\(\frac{1}{7}\) | |
| \(\frac{3}{13}\)x + \(\frac{3}{13}\) | |
| \(\frac{1}{14}\)x - \(\frac{4}{7}\) | |
| 2\(\frac{2}{5}\)x - \(\frac{1}{5}\) |
