a/ <=> y + 0,3y = -1,3
<=> 1,3y = -1,3
<=> y = -1
b/ <=> y - 1/4y = 1/2
<=> 3/4y = 1/2
<=> y = 2/3
c/ <=> 10/3y + 67/4 = -53/4
<=> 10/3y = -30
<=> y = -9
tìm y , biết
a, y+30%y=-1,3
b,y-25%y=1/2
c 3\(\frac{1}{3}\)y +16\(\frac{3}{4}\) = 13,25
tìm y biết
a) y+30%y=-1,3
b) y-25%y=1/2
c)\(3\frac{1}{3}\)y+\(16\frac{3}{4}\)=-13,25
Tìm y:
\(y+30\%y=-1,3\)
\(y-25\%y=\frac{1}{2}\)
\(3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
Tìm y, bt :
\(a.y+30\%y=-1,3\) \(b.y-25\%y=\frac{1}{2}\)
\(c.3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
Tìm x:
a, \(y+30\%y=-1,3\) b, \(y-25\%y=\frac{1}{2}\).
c, \(3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
Tìm y:
a, y+30%y= -1,3
b, y-25%y=1/2
c, 3+1/3y+16+3/4= -13,25
Tìm y , biết : ( cho mình xin cách giải nhé )
a) y - 25%y = \(\frac{1}{2}\)
b) 3\(\frac{1}{3}\)y + 16\(\frac{3}{4}\) = - 13,25
Tìm y:
y+ 30%.y= -1,3
y- 25%.y= 1\2
3 1\3. y + 16 3\4= -13,25
3 1\3 và 16 3\4 là hỗn số
Tìm y, biết:
a, y+\(\frac{3}{100}\).y=-1,3
b, \(3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
