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 5c - 9c = 6c - x + 6 for c in terms of x.
| -6\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| \(\frac{7}{17}\)x - \(\frac{1}{17}\) | |
| -8x - 6 | |
| \(\frac{4}{13}\)x - \(\frac{4}{13}\) |
