Noma'lum ayriluvchini topish

Noma'lum ayriluvchini topish uchun kamayuvchidan ayirmani ayirish kerak.

3- misol 38-z=12 tenglamani yeching.

38 - z = 12 Bu yerda “-z” tenglikning o’ng tomonida “+z” bo’lib o’tadi.

38=12+z “12” o’z navbatida tenglikning chap tomoniga “-12”

38-12=z bo’lib o’tadi.

z=26

38 - 26 = 12 to'g'ri tenglik. Javob: z = 26.

a)796 - z = 423; (J:373) 2609 - z = 1423 (J:1186)

1.Tenglamani ikki usulda yechib, uning to'g'ri yechilganligini tekshiring:

a) (x +24)-12 = 79; (J:67)

b) (y-29) + 45 = 76; (J:60)

Masala; Uchta kesmaning uzunliklari yig'indisi 143 dm. Birinchi kesma uzunligi x dm bo'lib, u ikkinchi kesmadan 23 dm qisqa, uchinchi kesmadan esa 21 dm uzun. Birinchi kesma uzunligini toping.

Yechim; masala shartiga ko’ra

1-kesma: xdm

2-kesma: xdm+23dm

3-kesma: xdm-21dm

Uchta kesmaning uzunligi x+x+23+x-21=143 bu tenglamani yechib

x+x+23+x-21=143

3x=143+21-23

3x=141

x=141:3

x=47

javob chiqaramiz. Bu 1-kesmaning uzunligi bo’ladi. Ikkinchi kesma xdm+23dm=47dm+23dm=70dm, uchunchi kesma 26dm.

Tenglamani yeching:

1) 8705-x=0 2) 25-y=12 3) 98-z=48

4) 7215-k=563 5) x-250=50 6) y-56=14

7) z-49=51 8) k-254=746 9) x+657=2777

10) 71+y=100 11) 45+z=65 12) 80+k=456

13) 5x-4x=15 14) 121y-254=120y 15) (12z-19)-11z=11

16) 8x-(15+7x)=5 17) 65-(13y+50)+14y=32 18) (45-x)-25=0

19) (x+375)-275=125 20) 69-(y+49)=0 21) 375-(25+y)=135

22) (948+a)-275=293 23) 139-(x+6)=129 24)(b+274)-116=161

25) 256-(144+y)=112 26) 800+(x-120)=1000 27) (x-940)+860=1000

28) (589+x)+300=1000 29) (x+666)+1001=2000 30) 345-(x-267)=17

31) Agar o’ylangan sondan 3125 ni ayirib , ayirmaga 2120 qo’shilsa , 8123 hosil bo’ladi . o’ylangan sonni toping .
