Question

2x + 3 = 5 . Solve for x

Answer 1

Answer:

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

Step-by-step 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 $\rm 1x = x$so,

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

Answer 2

Answer:

x = 1

Step-by-step explanation:

2x + 3 = 5

=> 2x = 5 - 3

=> 2x = 2

=> x = 2/2

=> x = 1
