Proszę o obliczenie i napisania z Obliczeniem sam wynik mnie nie interesuje dam naj 3 ( x-4)-2(2x-5)=-4 2(x+4)-5(x+3)=-2 -2(x+3)+4(2x+3)=-6 (3-2x)+(3x+4)=-(3-2x)+(5x+4) 3(x-4)-4(2x-7)=2(x+5) 2(2x-3)+3(4-x)=-(x+1)

Daje skan;)
3(x-4)-2(2x-5)=-4
3x-12-4x+10=-4
-x-2=-4
-x=-2
x=2
2(x+4)-5(x+3)=-2
2x+8-5x-15=-2
-3x-7=-2
-3x=5
-2(x+3)+4(2x+3)=-6
-2x-6+8x+12=-6
6x+6=-6
6x=-12
x=-2
(3-2x)+(3x+4)=-(3-2x)+(5x+4)
3-2x+3x+4=-3+2x+5x+4
x+7=7x+1
6x=6
x=1
3(x-4)-4(2x-7)=2(x+5)
3x-12-8x+28=2x+10
-7x=-6
2(2x-3)+3(4-x)=-(x+1)
4x-6+12-3x=-x-1
2x=-7
