Question 1204660
There are a total of 20 lions, tigers, and bears at the local zoo.

 The number of tigers is 2 more than the number of lions.

Let number of lions be x

Number of tigers will be x+2


 The number of bears is 3 more than the number of lions. 

The number of bears= x+3

Add them up. They equal 20

x+x+2+x+3=20

3x+5 =20

subtract 5 from both sides

3x+5-5= 20-5
3x=15

divide by 3

x=5
 There are 5 lions at the zoo.
