Question

Resolva as equações:

A) 3x-2 = 2x+4

B) 6x+7 = 4x + 11

C) 5x- 3x - 10 = x + 4

Answer 1

A) 3x-2 = 2x+4

3x - 2x = 4 + 2

x = 6

B) 6x+7 = 4x+11

6x-4x = 11 - 7

2x = 4

x = 4/2 = 2

C) 5x - 3x - 10 = x + 4

5x - 3x - x = 4 + 10

x = 14

Answer 2

a) 3x-2x = 4+2

   x = 6

b) 6x-4x = 11- 7

   x = 4/2

   x = 2

c) 2x - x = 4 +10

  x= 14
