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