Answer 1

Answer:

the solution is (1/2, -11/4)

Step-by-step explanation:

Given the system

x - 2y = 6

2x - 4y = 10

Multiply the second equation by -1/2, resulting in the revised system

       x - 2y = 6

       x + 2y = -5

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

       2x = 1, so x = 1/2.  

Subbing 1/2 for x in the first equation results in

1/2 - 2y = 6.

Multiply all terms by 2 to eliminate the fractional coefficient 1/2:

1 - 4y = 12, so y = -11/4

and the solution is (1/2, -11/4).
