H)2(x-3)+8x+4=5(x+2)

Answer 1

Vamos lá..

A)3(x+2)-1=2(x+3)-7

3x+6-1=2x+6-7

3x-2x=-1-5

x=-6

B)3(x+1)+2=5+2(×-1)

3x+3+2=5+2x-2

3x-2x=-2

x=-2

C)3(2x-3)+×=5

6x-9+x=5

7x=14

x=14/7=2

D)3x+5+2x+6=x+27

5x-x=11-27

4x=16

x=16/4=4

E)2(x-1)+3(x+1)=4(x+2)

2x-2+3x+3=4x+8

5x-4x=8-1

x=7

F)3(3x+8)-5x=x-3

9x+24-5x=x-3

3x=-27

x=-27/3=-9

G)5(2x-1)=3(x+10)

10x-5=3x+30

7x=35

x=35/7=5

H)2(x-3)+8x+4=5(x+2)

2x-6+8x+4=5x+10

5x=12

x=12/5
