E) x+15=29

Reposta completa pfvr

Answer 1

A 3x + 8 - x = 10

  2x = 10 - 8

  2x = 2

   x = 2/2

x = 1

B   3y - 12 + y = 12

    4y = 12 + 12

    4y = 24          y = 24/12    y = 2

C  x + 20 = 37

   x = 37 -20      x = 17

D   x - 32 = 18

    x = 18 + 32         x = 50

E x + 15 = 29

 x = 29 - 15       x =14
