Multiply 7x−3y=6 by 4. Add the resulting equations together.Multiply 3x+4y=−8 by 7. Multiply 7x−3y=6 by −3 . Add the resulting equations together.Multiply 3x+4y=−8 by 4. Multiply 7x−3y=6 by 3. Add the resulting equations together.Multiply 3x+4y=−8 by −3 . Multiply 7x−3y=6 by 7. Add the resulting equations together.

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:
