2(4x+1)=2(5x-7) ; 2(-x-5)=-8(3+-2) +56; 5 ( x-2) -7(x+3) +35=0 DAU COROANAAA​

Răspuns :

2(4x+1)=2(5x-7)

8x+2=10x-14

8x-10x=-14-2

-2x=-16

X=-16:(-2)

X=8

2(-x-5)=-8(3-2)+56

-2x-10=-8+56

-2x=48+10

-2x=58

X=58:(-2)

X=-26

5(x-2)-7(x+3)+35=0

5x-10-7x-21+35=0

5x-7x=0+10+21-35

-2x=-4

X=-4:(-2)

X=2
