Question

A) 10+(X-2)=5-(X+4)

B)2X+(5-X)=3-3X+6

C)4(X-2)-2(X+1)=4

D)10(X+1)-6=2.(-3)-10

E)2(X-2)+3(2X+2)=-5(2-X)

F)X+3(X-1)-2-3(X-3)=0

G)6X-4(X-5)-(5-3X)=0

H)3X-(X+11-1= -X+4(2-X)

Alguém pode me ajudar a resolver digamos que eu tenha um problemão aqui kk

Answer 1

A) 10+(X-2)=5-(X+4)
10+x-2=5-x-4
x+x=5-4-10+2
2x=1-10+2
2x=-9+2
2x=-7
x=-7/2


B)2X+(5-X)=3-3X+6
2x+5-x=3-3X+6
2x-x+3x=3+6-5
x+3x=9-5
4x=4
x=4/4
x=1

C)4(X-2)-2(X+1)=4
4x-8-2x-2=4
4x-2x=4+8+2
2x=12+2
2x=14
x=14/2
x=7

D)10(X+1)-6=2.(-3)-10
10x+10-6=-6-10
10x=-6-10-10+6
10x=-16-10+6
10x=-26+6
10x=-20
x=-20/10
x=-2

E)2(X-2)+3(2X+2)=-5(2-X)
2x-4+6x+6=-10+5x
2x+6x-5x=-10+4-6
8x-5x=-6-6
3x=-12
x=-12/3
x=-4

F)X+3(X-1)-2-3(X-3)=0
x+3x-3-2-3x+6=0
x+3x-3x=3+2-6
4x-3x=5-6
x=-1

G)6X-4(X-5)-(5-3X)=0
6x-4x+20-5+3x=0
6x-4x+3x=-20+5
2x+3x=-15
5x=-15
x=-15/5
x=-3

H)3X-(X+11-1)= -X+4(2-X)
3x-x-11+1=-x+8-x
3x-x+x+x=8+11-1
2x+x+x=19-1
3x+x=18
4x=18
x=18/4 simplifica por 2
x=9/2
