3) 4,07 – 5,49 + 8,93 – 1,51 4) – 11,401 – 23,17 + 4,401 – 10,83

2- misol . O’xshash xadlarni ixchamlang

1) 4a + 2b + a – b 3) 0,1c – 0,3 + d – c – 2,1d

2) x – 2y – 3x + 5y 4) 8,7 – 2m + n -

3- misol . O’xshash xadlarni ixchamlang

1) 2,3a – 0,7a + 3,6a – 1 4)

2) 0,48b + 3 + 0,52b – 3,7b 5) 2,1m + n – 3,2n + 2m + 1,1m – n

3) 6) 5,7p – 2,7q + 0,3p + 0,8q + 1,9q – p



4- misol. Ifodani soddalashtiring

1) 3(2x + 1) + 5(1 + 3x) 3) 10(n+m) – 4(2m + 7n)

2) 4(2 + x ) – 3(1 + x) 4) 11(5c + d) + 3(d + c)

5-misol. Ifodani soddalashtiring va son qiymatini toping

1)5(3x – 7) + 2(1 – x) , bunda x =



2) 7(10 – x) + 3(2x – 1) , bunda x= - 0,048

3)

4) 0,01(2,2x – 0,1) + 0,1(x – 100) , bunda x = -10
