Answer:

  • x = <u>1</u>

Step-by-step explanation:

In this question we are given with an equation that is<u> </u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>3 </u><u>=</u><u> </u><u>5</u><u> </u><u>.</u> And we are asked to find the value of <u>x</u><u> </u><u>.</u>

<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>

<u>\longmapsto \qquad \: 2x + 3 = 5</u>

<u>Step </u><u>1</u><u> </u><u>:</u> Subtracting with 3 on both sides :

\longrightarrow \qquad \:2x + \cancel{ 3} -  \cancel{3} = 5 - 3

On further calculations, We get :

\longrightarrow \qquad \:2x = 2

<u>Step </u><u>2</u><u> </u><u>:</u> Dividing with 2 on both sides :

\longrightarrow \qquad \: \dfrac{ \cancel{2}x}{ \cancel{2}}  =   \cancel{\dfrac{2}{2} }

On calculating further, We get :

\longrightarrow \qquad \:   \blue{\underline{\boxed{ \sf{x = 1}}}} \quad \bigstar

  • <u>Henceforth</u><u> </u><u>,</u><u> value</u><u> of</u><u> x</u><u> is</u><u> </u><u>1</u><u> </u><u>.</u>

<u>Verifying</u><u> </u><u>:</u><u> </u><u>-</u>

Now we are checking our answer by substituting value of x in the given equation . So ,

  • 2x + 3 = 5

  • 2 ( 1 ) + 3 = 5

  • 2 + 3 = 5

  • 5 = 5

  • L.H.S = R.H.S

  • Hence , Verified .

<u>Therefore</u><u> </u><u>,</u><u> </u><u>our</u><u> answer</u><u> is</u><u> correct</u><u> </u><u>.</u>

omeli [17]

False.

Replace x with 0 and solve:

2(0) + 3 = 0+ 3 = 3

3 is not greater than 13 so the answer is false.
