Answer:

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

Explanation:

Let

x ----> represent the number of home runs Lu hit

y ---> represent the number of home runs Karrine hit

we know that

Together they hit 10 home runs

so


x+y=10 ----> equation A

Karrine hit 4 more home runs than half the number of home runs Lu hit

so


y=(1)/(2)x+4 ---> equation B

substitute equation B in equation A


x+(1)/(2)x+4=10

solve for x


(3)/(2)x=10-4


(3)/(2)x=6\\x=4

Find the value of y


y=(1)/(2)(4)+4=6

therefore

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
