We have, 12x=54-6y .…(1)
-17x=-62-6y …..(2)
Now, subtracting equation (2) from equation (1), we get
12x -(-17x) = 54-6y - (-62 - 6y)
12x + 17x = 54-6y + 62 + 6y
29x = 116
Now,dividing both sides by 29, we get
29x/29 = 116/29
x = 4
Now, putting value of x in equation (1), we get
12(4) = 54-6y
48 = 54 -6y
6y = 54 -48
6y = 6
Now,dividing both sides by 6, we get
6y/6 = 6/6
y = 1
Thus, the value of x and y are 4 and 1 respectively.
