2x + 6y = –16

jhonyy9 · Answer

multiply first with 2 and the second with 5 and you get 

10x-18y=-32
10x+30y=-80     so after this subtract from first the second
--------------
  0   -48y=48
            y= 48/-48 = -1

y= -1

2x+6y= -16
2x+6(-1)= -16
2x -6 = -16
2x= -10
x= -10/2 = -5

x= -5
y= -1

jhonyy9 · Answer

2(-5)+6(-1)=-16
-10-6=-16
-16=-16
