Answer 1

Resposta:

Explicação passo-a-passo:

A) 5x+23=48 => 5x=48-23 => 5x=25 => x=25/5 x=5

B) 20+3x-2+8x=5x-44 => 3x+8x-5x = -44-20+2 => 6x = -62 => x= -62/6 => x = -31/3

C) 5x+3x=16 => 8x = 16 =>  x=16/8 => x=2

D) 7x-2-5x=18 => 2x =20 => x=10

E) 6x=2x+16  => 4x=16 => x=4

F) 4x-10=2x+2  => 2x = -8 => x=-4

G) 2x+1=4x-7 => 8=2x=> x=4

H) 3x-2=4x+9 => -9-2=x=>x=-11

I) 5x+4=3x-2x+4 => 5x-3x+2x =4-4=> 4x=0 => x=0/4 = 0

J) 5x+50 => 5x+50 = 0 => 5x= -50 => x= -11
