\(3\frac{1}{3}y+16\frac{3}{4}=13,25\)
\(\Rightarrow\frac{10}{3}y+\frac{67}{4}=13\frac{1}{4}\)
\(\Rightarrow\frac{10}{3}y+\frac{67}{4}=\frac{53}{4}\)
\(\Rightarrow\frac{10}{3}y=\frac{53}{4}-\frac{67}{4}\)
\(\Rightarrow\frac{10}{3}y=\frac{-14}{4}\)
\(\Rightarrow y=-\frac{14}{4}:\frac{10}{3}\)
\(\Rightarrow y=-\frac{14}{4}.\frac{3}{10}\)
\(\Rightarrow y=\frac{-21}{20}\)
Chúc bạn học tốt !!!
Tìm y, biết:
a, y+\(\frac{3}{100}\).y=-1,3
b, \(3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
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 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, 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 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 x \(3\frac{1}{3}x+16\frac{3}{4}=-13,25\)
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 x:
a, \(y+30\%y=-1,3\) b, \(y-25\%y=\frac{1}{2}\).
c, \(3\frac{1}{3}y+16\frac{3}{4}=-13,25\)
Bài 8 : Tìm x , biết :
\(3\frac{1}{3}x+16\frac{3}{4}=-13,25\)
