Question

giúp mình giải bài này với :

Tìm x :

a) X x 3 + 6 x X = 32607

b) 12 x X - X x 7 = 25350

c) 216 : X + 34 : X = 10

d) 2125 : X -125 : X = 100

Answer 1

`a, 9 x = 32607`

`x = 3623`

`b, 5x = 25350`

`-> x = 5070`

`c, 250: x = 10`

`-> x = 25`

`d, 2000 : x = 100`

`-> x = 20`

Answer 2

a.X x ( 3+6) = 32607

X x 9 = 32607

X = 3623

_ _ _ _ _ _ _ 

b. X x (12-7) = 25350

X x 5 = 25350

X=5070

_ _ _ _ _ _ _ _ 

c. (216 + 34) : X = 10

250 : X = 10

X = 25

_ _ _ _ _ _ _ 

d.(2125-125) : X = 100

2000 : X = 100

X = 20

Answer 3

\(a,3x+6x=32607\\ 9x=32607\\ x=32607:9\\ x=3623\\ ---------\\ b,12x-7x=25350\\ 5x=25350\\ x=25350:5\\ x=5070\\ ---------\\ c,\left(216+34\right):x=10\\ 250:x=10\\ x=250:10\\ x=25\\ ----------\\ d,\left(2125-125\right):x=100\\ 2000:x=100\\ x=2000:100\\ x=20\)

Answer 4

`a)`

`x xx 3 + 6 xx x = 32607`

`=>x xx ( 3+6)=32607`

`=>x xx 9=32607`

`=>x= 32607 : 9`

`=>x= 3623`

`b)`

`12 xx x - x xx 7 = 25350`

`=> (12-7) xx x  = 25350`

`=> 5 xx x  = 25350`

`=>x=  25350:5`

`=>x= 5070`

`c)`

`216 : x + 34 : x = 10`

`=>(216 +34 ) : x= 10`

`=> 250 : x= 10`

`=>x=250:10`

`=>x=25`

`d)`

`2125 : x -125 : x = 100`

`=>(2125 - 125) : x= 100`

`=> 2000 : x=100`

`=>x=2000:100`

`=>x=20`

Answer 5

a) X x 3 + X x 6 = 32 607

 X x ( 3 + 6 ) = 32 607

X x 9 = 32 607

X = 32 607 : 9

X = 3623

b) 12 x X - X x 7 = 25 350

X x ( 12 - 7 ) = 25 350

X x 5 = 25 350

X = 25 350 : 5

X = 5070

c) 216 : X + 34 : X = 10

( 216 + 34 ) : X = 10

250 : X = 10

X = 250 : 10

X = 25

d) 2125 : X - 125 : X = 100

( 2125 - 125 ) : X = 100

2000 : X = 100

X = 2000 : 100

X = 20
