Question

Which ordered pair is a solution of system 2x-y<5 and x +2y > 2

A) (1,-1)
B) (4,1)
C) (2,0)
D) (3,2)

Answer 1

D

Explanation: When you plug 3 into where x in the first equation and plug 2 in for y. When you do that you get 6-2<5, 6-2 is 4 and 4 is less than 5, so this makes this equation true. For the second equation you do the same. 3 goes into the x spot and 2 into the y, after doing this you get 3+2(2)>2, 3 times 4 is 12 and that is greater than 2, hich also means that equation is ture. So there you have both equations are ture and that is how you get your answer.
