2x/3+1/2=x/4-3/2

X/3-1+3/4=x/2-1/14

Answer 1

Resposta:

2x=16

x=16/2

 x=8

5x +4-2x=26-3x

5x -2x +3x= 26 -4

      6x=22

        x=22/6

         x=3,6

5m -7 -2m -2=0

5m-2m=7 +2

      3m=9

     m=9/3

      m=3

y -8 +5y= -3 +2y +7

 y +5y -2y= -3 +7 +8

   6y -2y= 4 +8

       4y = 12

         y=12/4

          y = 3

-10 +4 -2x= 4x -7

  -2x +4x = -7 +10 -4

         2x = 3 -4

           2x = -1

             x= -1/2

10x - 8 -2 = 7x -4

10x -7x = -4 +8 +2

     3x= 6

    x=6/3

     x=2

3.(x+2) +5 = x +12

 3x +6 +5 = x +12

    3x - x = 12 -6 -5

         2x = 1

            x=1/2

Espero ter ajudado!!!
