Answer 3

\[\frac{ 2x }{7 }+\frac{ 4 }{5}=5\]
Subtract
\[\frac{ 2x }{7 }+\frac{ 4 }{5}-\frac{ 4 }{5}=5-\frac{ 4 }{5}\]
=
\[\frac{ 2x }{7 }=\frac{ 25 }{ 5 }-\frac{ 4 }{ 5 }\]
=
\[\frac{ 2x }{7 }=\frac{ 21 }{ 5 }\]
Multiply by 7
\[\frac{ 2x }{7 }*7=\frac{ 21 }{ 5 }*7\]
=
\[2x=\frac{ 147 }{5 }\]
Divide by 2
=
\[2x*2=29.4*2\]
=
\[x=58.8\]
