7x - 3y = 4 multiple 4 on both sides;
28x - 12y = 16 (equation 1)
2x - 4y = 1 multiple 3 on both sides,
6x - 12y = 3 (equation 2)
equation 1 - equation 2 the result is:
22x = 13,
x = 13/22
7(13/22) - 3y = 4
(91/22) - 3y = 4
-3y = 4 - (91/22) = 88/22 - 91/22 = -3/22
y = (-3/22)/(-3) = 1/22
The solution for the system 7x - 3y = 4, 2x - 4y = 1 is (13/22, 1/22).
