Solve the following system by elimination:

{3 x + 11 y = 4 | (equation 1)

-2 x - 6 y = 0 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{3 x + 11 y = 4 | (equation 1)

0 x+(4 y)/3 = 8/3 | (equation 2)

Multiply equation 2 by 3/4:

{3 x + 11 y = 4 | (equation 1)

0 x+y = 2 | (equation 2)

Subtract 11 × (equation 2) from equation 1:

{3 x+0 y = -18 | (equation 1)

0 x+y = 2 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -6 | (equation 1)

0 x+y = 2 | (equation 2)

**x = -6 and y = 2**
