The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
Step-by-step 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

Find the value of y
therefore
The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
