Answer:


\boxed{ \boxed{\huge\bf \; x = 1}}

Explanation:


\underline{\bf \: Given \: equation:-}


2x + 3 = 5


\underline{ \bf \: To \: Find :-}


\rm Value\: of \: x


\underline{ \bf \: Solution :-}


\bf : \sf \longmapsto2x + 3 = 5


\underline{\rm Subtract \: 3\: from\: both \; sides:}


\bf : \sf \longmapsto2x + 3 - 3 = 5 - 3


\underline{\rm On \: Simplification:}


\bf : \sf \longmapsto2x + 0 = 2


\bf : \sf \longmapsto2x = 0


\underline{ \rm \: Divide \: both \: sides \: by \: 2 :}


\bf : \sf \longmapsto \: \cfrac{2x}{2} = \cfrac{2}{ 2}


\underline{\rm On \: Simplification:}


\rm Cancel \: 2 \: and \: 2 \: of \: LHS \: and \: then \: Cancel \: 2 \: and \: 2 \: of \: RHS(Leave\: x \: of \: LHS)


: \sf \longmapsto\cfrac{ \cancel2{x}}{\cancel2} = \cfrac{ \cancel2{}}{\cancel2}


\underline{\rm \: On \: Cancelling,}


: \sf \longmapsto1x = 1

As
\rm 1x = xso,


: \sf \longmapsto \: x =\boxed{ 1}
