Answer:

It is not correct.

Step-by-step explanation:

If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.

Hope this is helpful! :)

Answer:

undefined

Step-by-step explanation:

So with the following equation,

-2x + 5 = 13

we plug in 4 for x

-2(4) + 5 = 13

-2 * 4 = -8

-8 + 5 = 13

-8 + 5

-3 = 13

-3 is not 13 so it is undefined

Thus,

the answer is undefined.

Hope this helps :)
