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 - 4c = -7c + 7x + 9 for c in terms of x.
| 11x + 9 | |
| -\(\frac{3}{4}\)x - \(\frac{1}{4}\) | |
| -x - 3 | |
| \(\frac{1}{2}\)x + 2\(\frac{1}{2}\) |
