Question

4 Tìm x e Z biết :

x - 96 = ( 443 - x ) - 15

Answer 1

<=> x - 96 = 443 - x - 15

<=> x + x  = 443 - 15 + 96

<=>   2x   = 524

<=>   x     = 524 : 2

<=>  x      = 262

Answer 2

\(x-96=\left(443-x\right)-15\)

\(x-96=443-x-15\)

\(x+x==443-15+96\)

           \(x.2=524\)

               \(x=524:2\)

               \(x=262\)

Tk mk nhé(nếu đúng)!Thank you!

Answer 3

mình chịu

Answer 4

=> x -96 = 443-x -15
