tim x biet 2x+5/3x-1=1/13
bai 1)tim x biet
a )24-(36+5)=x
b)14-21=(13-x)-(15+8)
bai 2) tim x biet
a)17-x=-25+(-16+9)
b)3x-21=-19-(-2x)
tim x biet
45-(3x+9)/13=42
(x+1)+(2x+2)+.....+(20x+20)=1050
Tim x biet: x+1/1+2x+3/3+3x+5/5+...............+20x+39/9=22+4/3+6/5+................+40/39
giup mik voi tim x biet
1, 5-(3x+6)>-2x+1
2, -7.(x+2)-3x<6-11x
3, (x+1).(x+2)-x.(x+3)<4-x
4, 6-2x>17+(4-x)
tim x biet 2/3x-(70+10/11):(13/15+13/35+13/63+13/99)=-5
Tim x, biet:
a) (-5)-(x+5)=3-(2x-5)
b)2(x-3)-3(x-2)=3(x+1)-5(x-2)
C)4(1-2x)=(-3)-3(2+3x)
Giải ngay nhé, chiều mình đi học rồi.
