Question

70-5.(x-3)=45

 

Answer 1

70-5.(x-3)=45

⇒5.(x-3)=25

⇒x-3=5

⇒x=8

Answer 2

70-5x+15=45

70-5x=30

-5x=40

x=-8

Vậy x=-8

Answer 3

70-5(x-3)=45

nên x-3=5

hay x=8

Answer 4

70 - 5(x - 3) = 45

<=> 70 - 5x + 15 = 45

<=> -5x = 45 - 70 - 15

<=> -5x = -40

<=> x = 8

Answer 5

5.(x-3)=70-45

5.(x-3)=25

    x-3=25:5

    x-3=5

    x   =8

Answer 6

x=8
