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 6c - 3c = 7c - 4x - 9 for c in terms of x.
| -\(\frac{3}{4}\)x - 2\(\frac{1}{4}\) | |
| 1\(\frac{3}{5}\)x - \(\frac{3}{5}\) | |
| -2x + 1\(\frac{1}{2}\) | |
| x + 9 |
