Answer 4

\[\huge \frac{ 3 }{ 3x } + \frac{ 1 }{ x+4 } = \frac{ 10 }{ 7x }\]
\[\huge \frac{ 1 }{ x } + \frac{ 1 }{ x+4 } = \frac{ 10 }{ 7x }\]
\[\huge \frac{ 1(x+4) + 1(x) }{ x(x+4) } = \frac{ 10 }{ 7x }\]
\[\huge \frac{ 2x+4 }{ x^2 + 4x } = \frac{ 10 }{ 7x }\]
Cross multiply it now =)

Answer 5

8x and 4x

Answer 6

Cross multiply the terms... what do you mean 8x and 4x..

Answer 7

\[\huge (2x+4)(7x) = 10(x^2 + 4x)\]
Multiply, expand, get everything on one side.
