There are 17 animals in the barn. some are ducks and some are sheep. there are 48 legs in all. how many of each animal arr there?

x=10 , y=7

Step-by-step explanation:

x + y = 17

we know that ducks has 2 feet and sheep has 4 feet.

so, 2x + 4y = 48

x = 17 -y

2(17-y) + 4y = 48

34 - 2y + 4y = 48

2y = 48 -3 4

2y =1 4

y=7

x + 7 = 17

x = 17-7

x=10

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
