Answer:
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
----> equation A
Karrine hit 4 more home runs than half the number of home runs Lu hit
so
---> equation B
substitute equation B in equation A

solve for x


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

Answer:y=2/3x-2
Step-by-step explanation:
you need to get “Y” by itself therefore you subtract 2x on each side you will end up with -3y=-2x+6 then to get “Y” by itself you divide by -3 on both side and since there is a negative 2 on the other side a negative and a negative makes a positive and then you divide the 6 by -3 , that will give you y=2/3x-2
