x + 10 - (32 + 48 : 6 - 15) = 0
x + 10 - (32 + 8 - 15) = 0
x + 10 - 25 = 0
x = 0 + 25 - 10
x =15
bay gio mk ranh rui mk lam cho
x+5.2-(32+16.3:6-15)=0
x+5.2-(32+48:6-15) =0
x+5.2-(32+6-15) =0
x+5.2-(38-15) =0
x+5.2-23 =0
x+10-23 =0
x+10 =0+23
x+10 =23
x=23-10
x=13
chuc bn hoc gioi!
x+5.2-(32+16:3x6-15)=0
=> x+ 5+10-(32:32-15)=0
=> x+ 15- (-14)=0
=>x+15 +14=0
=> x= 0-14-15
=>x= -29
x phải = 15 ms đúng
