Question

a)4x-8=2x+10 b) 2x+34=4x+14 c) 6x-12=4x+14 d) 5x+20=10x+10​

Answer 1

Oi , tudo bem ?

A)

4x-8=2x+10

4x-2x=10+8

2x = 18

 X=18/2

  X=9

 

b)

2x+34=4x+14

2x -4x = 14-34

  -2x= -20

     x= -20/-2

      x=+10

c) 6x-12=4x+14

   6x -4x= 14+12

       2x = 36

         X=36/2

          x=18

d)

5x+20=10x+10​

5x -10x = 10-20

   -5x = -10

      x= -10/-5

       x= +2

Espero ter ajudado !

Bons estudos :)
