QuestionEvaluate $5 x-\frac{x}{y}$ when $x=4$ and $y=2$

Studdy Solution
First, calculate $5 \times 4$:
$$5 \times 4 = 20$$
Next, calculate $\frac{4}{2}$:
$$\frac{4}{2} = 2$$
Now substitute these results back into the expression:
$$20 - 2$$
Finally, perform the subtraction:
$$20 - 2 = 18$$
The evaluated result is:
$$\boxed{18}$$
