Accepted Solution

A:

The answer is А

Multiply 3x+4y=−8 by 3. Multiply 7x−3y=6 by 4:

{3x + 4y = -8 |*3

{7x - 3y = 6 |*4

{9x + 12y = -24

{28x - 12y = 24

Add the resulting equations together:

37х = 0

Multiply 3x+4y=−8 by 3. Multiply 7x−3y=6 by 4:

{3x + 4y = -8 |*3

{7x - 3y = 6 |*4

{9x + 12y = -24

{28x - 12y = 24

Add the resulting equations together:

37х = 0
