Answer 1

Ответ:

1)-9x+7x-5x+2x = -5x

2) 5a-6a+2a-10a = -9a

3) -3,8k-k+3,8k+k = 0

4) а + 6,2a-6,5a-а = -0,3k

5)2/9m+4/9m-3/9m-5/9m = -2/9 m

6) -18n-12n+ 7,3n +6,5n = -16,2n

7) -8x+5,2a+3x+50a = -5x + 55,2a

8) 5a-9,2m+7a+ 15m = 12a + 5,8m

9)2/7x-4/9y-5/14x+2/3y = 2/9y - 1/14x

l0) -6a+5a -x+4x = 3x - a

ll) 23x-23+40+4x = 27x + 17

l2) 4x-2a+6x-3a+4 = 10x - 5a + 4

l3) -6.3m+8-3,2m-5 = 3 - 9,5m

i4) 4a-6a-2a+12-ll = 1 - 4a

15)0.2m-2/9-4m+5/9 = 1/3 - 3,8m

19) 7,4x 5,3y +6,6x-3.7y
