Question 43.Solve: p + 1 = 2(a) 1(b) 2(c) -1(d) -2​

Answer 1

Answer :-

• The correct option is a).
• The value of p is 1.

Step-by-step explanation :-

Solve the equation :-

$\sf p + 1 = 2$

Transposing 1 from LHS to RHS, changing its sign,

$\sf p = 2 - 1$

On simplifying,

$\sf p = 1.$

So, the value of p is 1.

Verification :-

To check our answer, we just have to put 1 (value of p) in place of p and check whether the LHS = RHS.

Putting 1 in place of p, we get :-

$\sf 1 + 1 = 2$

On simplifying,

$\sf 2 = 2.$

Since LHS = RHS,

Hence verified! ✔️✔️

$\large \underline{ \underline{ \frak{ \color{peru}Given:}}}$

$\mapsto \sf{p + 1 = 2}$

$\large \underline{ \underline{ \frak{ \color{green}To \: find:}}}$

$\leadsto \sf{The \: value \: of \: \bf p.}$

$\large \underline{ \underline{ \frak{ \color{blue}According \: to \: Question:}}}$

$\dashrightarrow \sf{p + 1 = 2}$

Transposing 1 to R. H. S.

$\dashrightarrow \sf{p = 2 - 1}$

$\dashrightarrow \sf{p = 1}$

$\bf \underline{Hence,}$

$\longmapsto \sf{Option \: (b) \: is \: correct.}$

$\large \underline{ \underline{ \frak{ \color{indigo}Verification:}}}$

$\longrightarrow \sf{p + 1 = 2}$

Substituing the values, we get

$\longrightarrow \sf{1+ 1 = 2}$

$\longrightarrow \sf{2 = 2}$
