PLEASE HELP!! this is due really soon

y=310

x=415

Step-by-step explanation:

x= Holmes Junior High

y= Harper Junior High

x has 105 more students than y. so, x=y+105

and if x and y are merged, you'll have 725 students. so, x+y=725

now you have:

x=y+105

x+y=725

now you can put the x of the first equation, in the second equation to find y :

(y+105)+y=725

2y+105=725

2y=725-105

2y=620

y=310

now put y in either 1st or the second equation. I'm using the 1st equation:

x=310+105

x=415

if anything is unclear, ask freely.
