Question

18 1)x+8²-10²; 3) x - 24 - 16 5) 2² 35 7) * : 36 20 2) 115 + -18, 4) 60% - y -57%; 6) 1 - 8 8) 49 18'​

Answer 1

X+ 8 5/6 = 10 1/3

Х+53/6=31/3

Х=31/3-53/6

Х=62/6-53/6

Х=9/6=1 1/2

11 7/9+у= 13 1/18

У=13 1/18-11 7/9

У=235/18-106/9

У=235/18-212/18

У=23/18=1 5/18

Х- 24 2/7=16 3/8

Х=16 3/8+24 2/7

Х=40 21/56+16/56

Х=40 37/56

60 2/5 -у= 57 3/4

-у=57 3/4-60 2/5

-у=-3 15/20-8/20

-у=-3+7/20=-2 13/20

У=2 13/20
