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).
