Solve the system

anonymous · Answer

5x = 2y?

hero · Answer

You didn't exactly do that correctly.

hero · Answer

You have to subtract the proper numbers from both sides, not add

anonymous · Answer

still confused?

hero · Answer

You have two equations. Solve one of them for x or y, then plug that value into the other and solve

anonymous · Answer

what value though?

hero · Answer

Here, I'll help you out:

2x + y = 3x + y

y - y = 3x - 2x
0 = x

so x = 0. Plug that into the first equation and solve for y.

anonymous · Answer

Thats still confusing? You wont get a answer?

hero · Answer

Yes, you will bro. You're just not seeing it for some reason.

hero · Answer

(2x + y) + (3x + y) = 4x + 10

2x + 3x + y + y = 4x + 10
(2 + 3)x + 2y = 4x + 10
5x + 2y = 4x + 10
5x - 4x + 2y = 10
x + 2y = 10

Now plug in x = 0 and finish solving for y.

anonymous · Answer

y = 5?

hero · Answer

Yes, but you should have been able to do it without my help.

anonymous · Answer

it was just confusing the way you put it. sorry.
