Question

a)X-2=0 b)3x=27 c)2x+3x-9=4x-5 d)2(x+4)=0

Answer 1

a)X-2=0
    x = 2

b)3x=27
   x = 27/3 = 9

c)2x+3x-9=4x-5
   2x + 3x - 4x = -5 + 9
     x = 4

d)2(x+4)=0
   2x + 8 = 0
   2x = -8
      x = -4

Answer 2

Olá Bruna.

a)X-2=0
x=2

b)3x=27
x=27/3
x=9

c)2x+3x-9=4x-5
5x-4x=-5+9
x= 4

d)2(x+4)=0
2x+8=0
2x=-8
x= -8/2
x=-4
