2x + 6y = 30

6x – 2y = 50

3(2x + 6y = 30)

6x – 2y = 50

= 6x + 18y = 90 ... 1

6x – 2y = 50

by elimination

20y = 40

y = 2

x = (50 + 2y)/6

= 54/6

= 9

x=9, y= 2

Answer:

The value of x=9 and y=2

Step-by-step explanation:

Taking a look at the question, we can assume that we have to find out the values of x and y.

The given equations are:

2x + бу = 30     (1)

6x - 2y = 50     (2)

Multiply the equation (2) by 3

I will become 18x - 6y = 150    (3)

Now add (1) and (3)

   2x + бу = 30

+  18x - 6y = 150

_____________

         20x = 180

x=9

Putting value of x in (1)

2(9) +6y =30

18 + 6y=30

6y=12

y=2

The value of x=9 and y=2
