Question

70-50.(x-3) =45

Answer 1

50.(x-3)= 70-45

70- 45= 

Answer 2

50.(x-3)=25

x-3=0,5

x=3,5

Answer 3

70-50.(x-3) =45

50.(x-3)=70-45

50.(x-3)=25

x-3=25:50

x-3=\(\dfrac{1}{2}\)

x=\(\dfrac{1}{2}+3\)

x=3,5

Vậy x=3,5

Answer 4

70 – 5.(x – 3) = 45

5.(x -3) = 70 - 45

5.(x – 3) = 25

x – 3 = 25 : 5

x – 3 = 5

x = 5 + 3

x = 8

Vậy x = 8
