Question

Biết \(\frac{4x}{6x}=\frac{2x+8}{3y+11}\) . Vậy \(\frac{x}{y}\)=

Answer 1

6y nha lộn á

Answer 2

4x/6x =2/3

2x+8/3y+11=2/3=> 3x=3y

x/y=3/3 = 1

x/y=1

Answer 3

\(\frac{4x}{6x}=\frac{2y+8}{6y+11}\Rightarrow\frac{4}{6}=\frac{2y+8}{6y+11}\Rightarrow\frac{2y+8}{6y+11}=\frac{2}{3}\)

=>(2y+8).3=(6y+11).2

=>6y+24=12y+22

=>12y-6y=24-22

=>6y=2=>y=2/6=1/3

sau đó tự tìm x nhé

Answer 4

Có \(\frac{4x}{6y}=\frac{2x+8}{3y+11}\Rightarrow4x\left(3y+11\right)=6y\left(2x+8\right)\)

    \(\Rightarrow12xy+44x=12xy+48y\)

    \(\Rightarrow44x=48y\)

      (Bỏ 2 vế cho 12xy)

   \(\Rightarrow\frac{x}{y}=\frac{48}{44}=\frac{12}{11}\)
