Answer:

X=1.5,y=2.5

Step-by-step explanation:

By elimination method

U have to make either x or y values equal and then eliminate it

The y values have a common value 12

By multiplying 6×2 and 3×4

2(4x+6y)=(21)2

4(7x-3y)=(3)4

8x+12y=42

+

28x-12y=12

36x=54

X=54/36=1.5

Substitute x with 1.5

Y=2.5
