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 8c + 9c = 9c - 4x + 4 for c in terms of x.
| -1\(\frac{1}{2}\)x + \(\frac{1}{6}\) | |
| 1\(\frac{3}{4}\)x - 1 | |
| 13x - 4 | |
| -\(\frac{6}{11}\)x - \(\frac{9}{11}\) |
