Answer:

x = -4, y = 1/3

Step-by-step explanation:

=> x = 3y-5        (Equation 1)

=> 2x+12y = -4  (Equation 2)

Putting (1) in (2)

=> 2(3y-5)+12y = -4

=> 6y-10+12y = -4

=> 18y = -4+10

=> 18y = 6

Dividing both sides by 18

=> y = 6/18

=> y = 1/3

Putting y = 1/3 in Equation 1

=> x = 3(1/3)-5

=> x = 1-5

=> x = -4

x=3y-5
2x+12y=-4

(-2)x=-6y+10
2x+12y=-4
12y=6
y=1/2

x=3y-5
2x+12y=-4

(-4)x=-12y+20
2x+12y=-4
-2x=16
x=-8
