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 - 7c = 8c + x + 2 for c in terms of x.
| -x - \(\frac{2}{3}\) | |
| 10x + 6 | |
| 8x + 2 | |
| -\(\frac{5}{6}\)x - 1\(\frac{1}{2}\) |
