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 -5c + 9c = 9c - 6x + 8 for c in terms of x.
| -\(\frac{1}{3}\)x + 2\(\frac{2}{3}\) | |
| -2x - \(\frac{6}{7}\) | |
| 1\(\frac{1}{14}\)x - \(\frac{4}{7}\) | |
| x + 1\(\frac{1}{2}\) |
