Question

ME AJUDEM E PARA HOJE AS 20H!!! SE PUDEREM FAÇAM AGORA

A) 5X - 4 = 3X + 26
B) 6X -2 + 2X = 3X + 12 +3X
C) 2X + 10 = 32
D) X - 9 = 27

Answer 1

Resposta:

a) 5x - 4x = 3x+26

5x-4x-3x =26

-2=26

-2x(-1)= 26(-1)

2x = -26

x= 26/2

x= 13

B) 6X -2 + 2X = 3X + 12 +3X

6x + 2x -3x-3x = 12+2

2x= 14

x= 14/2

x= 7

c)2X + 10 = 32

2x= -10+32

2x= 22

x= 22/2

x=11

d)X - 9 = 27

x= 27 +9

x= 36
