Question

Tìm x biết

53-5(x-3)=38

giúp mk vs nha

Answer 1

53-5(x-3)=38

5(x-3)=53-38

5(x-3)=15

x-3=15:5

x-3=3

x=3-3

x=0
Vậy x=0

Answer 2

53-5(x-3)=38

53-5x+15=38

-5x=38-53-15

-5x=-30

x=\(\dfrac{-30}{-5}\)=\(\dfrac{30}{5}\)=6

vậy x =6

Answer 3

53 - 5( x-3 ) = 38

53 - 5x - 15 = 38

5x - 15 = 53-38

5x - 15 = 15

5x = 15 - 15

5x = 0

=> x = 0

Answer 4

\(53-5\left(x-3\right)=38\)

\(=5\left(x-3\right)=53-38\)

\(=5\left(x-3\right)=15\)

\(x-3=15:5\)

\(x-3=3\)

\(x=3+3\)

\(x=6\)
