What is the value of 4x-1/2y-12 when x=5 and y=20

the answer is - 2

Step-by-step explanation:

Since x=5 and y=20, plug those values into the correct variables in the equation of 4x-1/2y-12.

When we do that it brings us to:

4 (5) - 1/2 (20) - 12

Then we just simplify:

20-10-12

Simplify again:

10-12

So 10-12 is - 2, therefore - 2 is the answer
