Question

70-5(x-3)=45

Answer 1

=>5(x-3)=70-45

=>5x-15=25

=>5x=40

=>x=8

Answer 2

70-5(x-3)=45

=>5(x-3)=70-45

=>x-3=25:5

=>x=5+3

=>x=8

Answer 3

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

Answer 4

70-5x+15=45

70-5x=30

5x=40

x=8

Answer 5

\(70-5\left(x-3\right)=45\\ 5\left(x-3\right)=70-45\\ 5\left(x-3\right)=25\\ x-3=25:5\\ x-3=5\\ x=5+3\\ x=8\)

Answer 6

<=> 70 - 5x +15= 45

<=> 5x = 40

<=> x = 8

Answer 7

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
