Answer 1

1) W/3 - 1/5 = 2/3 + (W+5)/2

(5W-3)/5 = (4+3W+15)/2

10W-6 = 20+15W+75

-101=5W

-101/5=W

2) 0,1X-0,12 = 0.3X + 0.4

1/10x - 3/25=3/10x + 2/5

(5x-6)/5= (3x+4)

5x-6=15x+20

-26=10x

-13/5=x

3) (3x+5)/2 - (4x-5)/3 = (7x+1)/6 - 5

[9x+15-(8x-10)]/6 = (7x+1-30)/6

x+25=7x-29

54=6x

9=x

4) (x+2)/12 - (2x-3)/9 = (4-3x)/18 + x/6

[3x+6-(8x-12)]/36 = (4-3x+3x)/18

3x+6-8x+12 = 8-6x+6x

-5x+18 = 8

10 = 5x

2 = x
