~nha bn~
x + 20 x 5 = 60 + 200
x + 20 x 5 = 260
x + 20 = 260 : 5
x + 20 = 52
x = 52 - 20
x = 32
k nha
x+20.5=60+200
x+100 =60+200
x+100 =260
x=260-100
x=160
chuc bn hoc gioi!@
x + 20 x 5 = 60 + 200
x + 20 x 5 = 260
x + (20 x 5) = 260
x + 100 = 260
x = 260 - 100
x = 160
x + 20 x 5 = 60 + 200
x + 100 = 260
x = 260 : 100
x = 2,6
x+20.5=60+200
x+100 =260
x =260-100
x =160.
x + 20 x 5 = 60 + 200
x + 100 = 260
x = 260 - 100
x = 160
x + 20 x 5 = 60 + 200
x + 100 = 260
x = 260 - 100
x = 160
x + 20 x 5 = 60 + 200
x + 100 = 260
x = 260 - 100
x = 160
x+20x5=60+200
x+20x5=260
x+100=260
x=260-100
x=160
Vậy x=160
Mik nhanh nhất,giúp đỡ mik vài *** nha
=>160 ai cũng đã bít
ung ho tui ha
