Question

1- Determine a raiz de cada equação ( resolva descobrindo o valor do termo x desconhecido.)
A) 3x+2=2x-11
B) 2x=16
C)x+4.(x-1)=9-2.(x+3)
D) 4x-5=6x+11

Answer 1

A) 3x+2=2x-11
3x-2x= -11-2
x=13

B) 2x=16
 x=16/2
 x=8

C)x+4.(x-1)=9-2.(x+3)
x+4x-4=9-2x+6
5x-4=-2x+15
5x+2x=15+4
7x=19

D) 4x-5=6x+11
4x-6x=11+5
-2x=16
x=-8

Espero ter ajudado ;)

Answer 2

A)3x-2x=-11-2
    x=-13

B)2x=16
    x=16/2
    x=8
