Question

Lucy and Lila received 105 combined likes on their social media posts. Lila has 37 fewer likes than Lucy.

Enter the number of likes that Lucy received.

Answer 1

71

Explanation:

Note that a=Lila and y=Lucy (for the last letter of their names)

Set up this problem with 2 equations.

a+y=105

a+37=y

I hope it makes sense as to why you would set up the second equation like that. Anyway, go ahead and plug in y, to the first equation.

a+(a+37)=105

2a+37=105

2a=68

a=34

Now that you know how many likes Lila had, just add 37 to 34 to get Lucy's number of likes.

So Lucy has 71 likes!

Hope this helps!
