Jai has 35 pieces of fruit. They are all apples and pears. He has 15 more apples than pears. How many pears does he have?
number of pears --- x
number of apples --- x+15
solve for x:
x + x+15 = 35
35-15=20
To solve this problem, we can set up a system of equations. Let's assume that Jai has x number of pears. Since he has 15 more apples than pears, the number of apples he has is x + 15.
We know that the total number of fruit Jai has is 35. So we can write the equation:
x + (x + 15) = 35
Simplifying this equation, we get:
2x + 15 = 35
Subtracting 15 from both sides, we have:
2x = 20
Dividing both sides by 2, we find:
x = 10
Therefore, Jai has 10 pears.
