Question

porfa nadie me ayuda :(

Answer 1

Respuesta:

Explicación paso a paso:

(3x+x/2 -6)÷5x=11/20

(6x+x-12 /2)÷5x= 11/20

(7x-12 /2) × 1/5x =11/20

7x-12 /10x =11/20

20(7x-12)=11(10x)

140x-240=110x

140x-110x=240

30x=240

x=240/30

x=8

-----------------

x+2 /3 + x/2 =4

2x+4 +3x /6 =4

5x+4=6×4

5x=24-4

5x=20

x=20/5

x=4

------------------------

x/4 +x/3 =2x-17

3x+4x /12 =2x-17

3x+4x=24x-204

3x+4x-24x=-204

-17x=-204

x=-204/-17

x=12

---------------------

x + 3x/4 +9x/16 =185

16x+12x+9x /16 =185

37x=185

x=185/37

x=5
