Answer 2

Respuesta:

1/3 x + 1/2 x + 3/10 = x + 5/6 ; m.c.m( 3,2,10 ) = 30

30(1/3)x+30(1/2)x+30(3/10) = 30(x)+30(5/6)

10x+15x+3(3) = 30x+5(5)

25x+9 = 30x+25

25x-30x = 25-9

-5x =,16

-5x/-1 = 16/-1

5x = -16

5x/5 = -16/5

x = -16/5

1/3 x + 1/4 = 2/5 (x -3/4)

1/3x+1/4 =2/5x-6/20 , 6/20 = 3/10

1/3x+1/4 = 2/5x-3/4; m.c.m(3,4,5) = 60

60(1/3)x+60(1/4) = 60(2/5)x-60(3/4)

20x+15 = 12(2x)-15(3)

20x+15 = 24x-45

(20-24)x = -45-15

-4x = -60

-4x/-1 = -60/-1

4x = 60

4x/4 = 60/4

x = 15

- 3/2 (x - 1/6) =1/2 (x + 1)

-3/2x-3/12 = 1/2x+1/2 , 3/12 = 1/4

-3/2x-1/4 = 1/2x+1/2 ; m.c.m ( 2,4 ) = 4

4(-3/2)x-4(1/4) = 4(1/2)x+4(1/2)

2(-3x)-1 = 2x+2

-6x-1 = 2x+2

-6x-1-2x = 2x+2-2x

-8x-1 = 2

-8x-1+1 = 2+1

-8x = 3

-8x/-1 = 3/-1

8x = -3

8x/8 = -3/8

x = -3/8
