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 9c + 9c = -4c + 2x + 8 for c in terms of x.
| -4x + 2 | |
| -9x + 4 | |
| 11x + 3 | |
| -\(\frac{7}{13}\)x + \(\frac{8}{13}\) |
