x x 500 = 100
Tính giá trị biểu thức :
a) 500 + 500 + 500 + ( 100 x 2 )
b) 700 + 300 + ( 100 x 10)
a, 500+500+500+(100 x 2)
=500 x 3+ 100x2
=1500+200
=1700
b, 700+300+(100 x 10)=700+300+1000=1000+1000=2000

3 cái nhé
a) x= -300 -100
x = -400
b) x= -300 +100
x= -200
1)x+100=200-500
x+100=-300
x=-300-100
x=-400
2)x-100=200-500
x-100=-300
x=-300+100
x=-200
\(x+100=200-500\)
\(x+100=-300\)
\(x=-300-100\)
\(x=-400\)
\(x-100=200-500\)
\(x-100=-300\)
\(x=-300+100\)
\(x=-200\)
x + 100 = 500 + 500
x + 100 = 500 + 500
x + 100 = 1000
x = 1000 - 100
x = 900
Tk mk nha
x + 100 = 500 + 500
x + 100 = 1000
x = 1000 - 100
x = 900
Vậy x = 900
k nha
Tìm x :

x + 100 = 500 - 100
x + 100 = 400
x = 400 - 100
x = 300
Vậy x = 300
