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 - 6c = 7c + 4x + 8 for c in terms of x.
| 2x - 9 | |
| x - \(\frac{1}{2}\) | |
| -10x - 8 | |
| -1\(\frac{1}{10}\)x - \(\frac{3}{10}\) |
