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