Tìm x :
x + 100 = 500 - 100
Tìm x,
x+100=500-100
\(x+100=500-100\)
\(x+100=400\)
\(x=400-100\)
\(x=300\)
x+100=500-100
x+100=400
x=400-100
x=300
Ai tk mk mk tk laij lun
x + 100 = 500 - 100.
x + 100 = 400.
x = 400 - 100.
x = 300.
Kích mình nha!!!
Tìm x :
120 + 80 = 500 - x
100 + 100 = 400 - x
\(120\)\(+\)\(80\)\(=\)\(500\)\(-\)\(x\) \(100\)\(+\)\(100\)\(=\)\(400\)\(-\)\(x\)
\(200\) \(=\)\(500\)\(-\)\(x\) \(200\) \(=\)\(400\)\(-\)\(x\)
\(500\)\(-\)\(200\)\(=\)\(x\) \(400\)\(-\)\(200\)\(=\) \(x\)
\(300\) \(=\) \(x\) \(200\) \(=\) \(x\)
120 + 80 = 500 - x
200 = 500 - x
x = 300
100 + 100 = 400 - x
200 = 400 - x
x = 200
120 + 80 = 500 - x
100 + 100 = 400 - x
Ta có :
120 + 80 = 500 - x
=> 500 - x = 200
=> x = 300
Lại có :
100+100=400-x
=> 400-x = 200
=> x = 200
Tìm x :
102 + x = 257 b) 500 – x = 100
a) 102 + x = 257
x = 257 – 102
x = 155
b) 500 – x = 100
x = 500 – 100
x = 400
Tìm x :
x + 100 = 500
Tìm x :
x + 100 = 500
x + 100 = 500
x = 500 - 100
x = 400
Vậy x = 400
K mk nha
Mk k lại
Tìm x : [ 500 : (x - 10) x 2 ] + 100 = 200
Tìm x :
[ 500 : (x - 10) x 2 ] + 100 = 200
=> 500 : ( x - 10 ) x 2 = 200 - 100
=> 500 : ( x - 10 ) x 2 = 100
=> 500 : ( x - 10 ) = 100 : 2
=> 500 : ( x - 10 ) = 50
=> x - 10 = 500 : 50
=> x - 10 = 10
=> x = 10 + 10
=> x = 20
Vậy x= 20
Tìm x : [ 500 : (x - 10) x 2 ] + 100 = 200
[500 : (x-10) x 2] + 100 = 200
500 : (x-10) x 2 = 100
=> 500 : (x-10) = 50
=> x - 10 = 10
=> x =20
Tìm x :
x + 500 = 100 x 2
x+500=100x2
x+500=200
x=200-500
x=-300
đúng rồi bn nhé
*** mk nha
x + 500 = 100 x 2
x + 500 = 200
x = 200 - 500
x = - 300
Vậy x = - 300
Như vầy có đúng ko nhỉ ?
x + 500 = 100 x 2
x + 500 = 200
x = 200 - 500
x = -300
Nhớ tk cho mk nha mọi người
Tìm x :
x + 500 = 100 x 6
x + 500 = 100 x 6
x + 500 = 600
x = 600 - 500
x = 100
tk nha
