Question

How to writing system of linear equations. There are 160 lions and antelopes. The number of antelopes is forty less than triple the number of lions. How many of each animal is there?

Answer 1

Answer:Antelopes =110 and

Lions= 50

Step-by-step explanation:

Let antelopes be x and lions be y

x + y = 160. ........(1)

x= 3y - 40

Substitute x into equation 1

3y-40+y=160

4y= 160+40

4y = 200

Y=200/4

y=50

From equation

x=3y-40

x=3(50)-40

x=150-40

x=110

Antelopes =110

Lions= 50
