2x+1y=3740

You can use elimination to solve, which is where you multiply one or more equations to eliminate either the x's or y's.

Multiplying the top equation by negative 2 will cancel the x's.

-2x-4y=-5240

2x+1y=3740

Add the equations together.

-3y=-1500

Divide by negative 3.

y=500

Plug y=500 into any of the equations to figure out what x equals. Post if you want it checked.
