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 = 7c - 9x + 4 for c in terms of x.
| -\(\frac{1}{17}\)x - \(\frac{6}{17}\) | |
| -\(\frac{3}{7}\)x - \(\frac{3}{7}\) | |
| -\(\frac{1}{9}\)x + \(\frac{2}{9}\) | |
| x - 2 |
