A. because of

52×x+48×x= 100
x × (52+48) = 100
x × 100 = 100
x = 100 : 100
x = 1

-37.(-19)+37.(-119)
= 37.19-37.119
= 37.(19-119)
= 37. (-100)
= -3700

(29-9).(-9)+(-13-7).21
= 20.(-9)+(-20).21
= -20.9-20.21
= 20.(-9-21)
= 20.(-30)
= -600

12.(-47)+12.(-19)+(-66).88
= -12.47-12.19-66.88
= 12.(-47-19)-66.88
= 12.(-66)-66.88
= -12 . 66  - 66 . 88
= 66 . (-12-88)
= 66 . (-100)
= -6600

=> x = -8

c) 2x +1 = -5
=> 2x = -5 -1
=> 2x = -6
=> x = -6 : 2
=> x = -3

d) (-5) . x + 30 = 0
=> (-5) . x = 0 - 30 = -30
=> x = -30 : (-5)
=> x = 6

B tham khảo nhé
