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 c + 7c = 4c - x + 2 for c in terms of x.
| 2\(\frac{1}{4}\)x - 2\(\frac{1}{4}\) | |
| \(\frac{4}{5}\)x + 1\(\frac{3}{5}\) | |
| 2\(\frac{2}{3}\)x - \(\frac{2}{3}\) | |
| \(\frac{1}{10}\)x - \(\frac{1}{2}\) |
