The solution of linear equation with one variable There are 18 tigers and ostriches in the zoo, with a total of 44 feet. How many tigers and ostriches are there in the zoo? The solution of linear equation with one variable
Suppose tiger OIL X ostriches have 18-x
So 4x + 2 (18-x) = 44
X=4
There are 14 ostriches
