In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

3x - 2y = 11 eq. 1

-x + 6y = 7 eq.2

x = ?

y = ?

Step 02:

3x - 2y = 11

-x + 6y = 7 * (3)

3x - 2y = 11

-3x + 18y = 21

-----------------------

16y = 32

y = 32 / 16 = 2

y in eq. 1

3x - 2y = 11

3x - 2(2) = 11

3x - 4 = 11

3x = 11 + 4

x = 15 /3 = 5

The answer is:

x = 5

y = 2
