Sarah hit 8 home runs.
We are comparing everything to Larry, so we make Larry X.
We know that Sarah hit two times what Larry hit plus 4.

So Sarah hit ( 2*X + 4 )

Now we add in what Larry hit (X)

(2*X + 4) + X

Remember, alltogether they hit 10 home runs

(2*X + 4) + X = 10

Now combine like terms (X's) Remember 2*X= 2X

2X + X + 4 = 10
3X + 4 = 10

Now combine the numbers without variables

3X= 10-4
3X=6

Now divide both sides by three to get the X by itself

3X/3 = 6/3
X=2

Larry hit 2 home runs, so Sarah hit 8

Larry hit x home runs.
Sara hit 2x+4 home runs.

x + 2x + 4 = 10
3x + 4 = 10
3x = 6
x = 2

Larry hit 2 home runs and Sara hit 8.

Sara= 4+2x
Larry= x
10=4+ 2x + x
10=4+ 3x
6=3x
2=x

now plug in x

4+2(2)
4+4
8

Sara hit 8

let larry hits x
then sara hits 2x+4
so :
x+(2x+4)=10
3x=6
x=2
