Question

¿Cuál es la expresión algebraica correcta?
2.(3x)+2(x)=16
2 ( 3+2x)=16
16 = 3x + 2x
3x – x =16

Answer 1

2(3x)+2(x)=16

6x + 2x = 16

8x = 16

x = 16/8

x = 2
--------------------------
2 ( 3+2x)=16

6 + 4x = 16

4x = 16 - 6

4x = 10

x = 10/4

x = 5/2
------------------------------


16 = 3x + 2x

16 = 5x

16/5 = x

x = 16/5
-----------------------------------

3x - x = 16

2x = 16

x = 16/2

x = 8
