Determine the value of x in the system of equations.

3x+2y=25

6x-y=40

I got 7 if you are trying to look for the value of x than you multiply the bottom by two to have the y's equal. It should be

3x+2y=25

12x-2y=80

Since the twos mark each other out it would be

3x=25

12x=80

You add the top and bottom so it becomes one like this

15x=105

Divide 15 on both sides and it should give you 7.

X=7
