Answer:

3x-y= -13—1

y=5x-19—2

substitute equation 2 into equation 1

3x-(5x-19)= -13

3x-5x+19= -13

collect like terms

3x-5x= -13-19

-2x=-32

divide both sides by the coefficient of x

-2x/-2=32/-2

x= -16

substitute x= -16 into equation 2

3x-y= -13

3(-16)-y= -13

-48-y= -13

collect like terms

-y= -13+48

-y=35

y=-35
