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