Y=8-2x when x=8 the value of y

-8

Step-by-step explanation:

Given that x and y are two variables. they are related by the function

y = 8-2x

Since x and y are related, given one value we can find the other using this equation.

In our question, given that x = 8

Substitute x value in the equation

y = 8-2x

y = 8-2 (8) = - 8

Hence answer is - 8:

Verify: We verify by putting - 8 for y and check whether x = 8

-8=8-2x

Or 2x = 16

x = 8

Verified

I believe your answer to this question is

8
