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 -8c - 3c = 9c + 4x - 9 for c in terms of x.
| -\(\frac{7}{17}\)x + \(\frac{9}{17}\) | |
| \(\frac{1}{2}\)x - 4\(\frac{1}{2}\) | |
| -1\(\frac{1}{15}\)x + \(\frac{7}{15}\) | |
| -\(\frac{1}{17}\)x + \(\frac{8}{17}\) |
