Question

Calcula: 3x + 6 + 4x - 2 + 5x - 4 + 6x = 36

Answer 1

Respuesta:

3x + 6 + 4x - 2 + 5x - 4 + 6x = 36

3x+4x+5x+6x= 36-6+2+4

18x= 36

x= 36/18

x= 2

Answer 2

x = 2

Comprobamos:

3(2) + 6 + 4(2) - 2 + 5(2) - 4 + 6(2) = 36

6 + 6 + 8 -2 + 10 - 4 + 12 = 36

12 + 8 -2 + 10 - 4 + 12 = 36

20 -2 + 10 - 4 + 12 = 36

18 + 10 - 4 + 12 = 36

28 - 4 + 12 = 36

24 + 12 = 36

36 = 36
