Answer 2

Respuesta:

15x-10 = 6x-(x+2)+(-x+3)..

15x-10 = 6x-x-2-x+3

15x-10 = 5x-2-x+3

15x-10 = 4x+1

15x-4x = 1+10

11x = 11

11x/11 = 11/11

x = 1

4m+1/3+m = 4m-3/4

5m+1/3 = 4m-3/4 ; m.c.m(3,4) = 12

12(5m)+12(1/3) = 12(4m)-12(3/4)

60m+4 = 48m-3(3)

60m+4 = 48m-9

4+9 = 48m-60m

13 = -12m

13/-1 = -12m/-1

-13 = 12m

12m = -13

12m/12 = -13/12

m = -13/12

4d+8 = 3d-15

(4-3)d = -15-8

d = -15-8

d = -23

15m-[4m-(-4m+5) ] = 30m+[-(2m+2)-(m+3)]

15m-[ 4m+4m-5 ] = 30m+[-2m-2-m-3]

15m-[ 8m-5 ] = 30m+[ -3m-5 ]

15m-(8m-5) = 30m+(-3m-5)

15m-8m+5 = 30m-3m-5

7m+5 = 27m-5

(7-27)m = -5-5

-20m = -10

-20m/-1 = -10/-1

20m = 10

20m/2 = 10/2

10m = 5

10m/5 = 5/5

2m = 1

2m/2 = 1/2

m = 1/2
