-3x-5y=-6 6x+5y=-34 how do i solve this using elimination?

First you add the equations. -5y and 5y cross each out so you are left with 3x=-40 X= -40/3 Plug x back into one of the equations -3x-5y=-6 -3(-40/3)-5y=-6 -40-5y=-6 -5y= 34 Y=34/-5

Correction: It should be positive 40-5y=-6 So -5y=-46 Y=46/5
