Answer 4

\[\frac{ x }{x+5 }=\frac{ x-2 }{x+1 }\]
\[x \left( x+1 \right)=\left( x-2 \right)\left( x+5 \right)\]
\[x ^{2}+x=x ^{2}+5x-2x-10\]
x-5x+2x=-10
-2x=-10
x=5
or
\[\frac{ x }{ x+x+5 }=\frac{ x-2 }{ x-2+x+1 }\]
\[\frac{ x }{ 2x+5 }=\frac{ x-2 }{2x-1 }\]
\[x \left( 2x-1 \right)=\left( x-2 \right)\left( 2x+5 \right)\]
\[2x ^{2}-x=2x ^{2}+5x-4x-10\]
-x-5x+4x=-10
-2x=-10
x=5

Answer 5
