1. Wyznaczając x z równania 3x-2y=5 otrzymamy:
2. Z tego ukł. równań otrzymamy:
2x-y=4
3x-2y=2
1.
3x - 2y = 5
3x = 5-2y /:3
x= (5-2y)/3
2.
2x - y = 4 /* (-2)
3x - 2y = 2
-4x + 2y = -8
---------------
-x = -6 /* (-1)
x = 6
2*6 - y = 4
12-y = 4
-y = 4 - 12
-y = -8 /* (-1)
y= 8
3x-2y=5
3x=5+2y/3
x=5+2y/3
2x=4+y/2
x=4+y/2
3*(4+y/2)-2y=2
(12+3y)/2-2y=2/*2
12+3y-4y=4
-y=-8/*-1
y=8
x=4+8/2
