Question

Which value of $p$ makes the equation $p+6=5$ true$?$

• A. $-1$
• B. $1$
• C. $11$
• D. $30$

Answer 1

The correct option is A

$-1$

Explanation for the correct option

The given equation is $p+6=5$

Substituting $p=-1$in the given equation, we get

$\Rightarrow -1+6=5$

$\Rightarrow 5=5$

So, $\text{LHS=RHS}$

Explanation for incorrect options

Substituting $p=1$in the given equation, we get

$\Rightarrow 1+6\ne 5$

$\Rightarrow 7\ne 5$

So, $\text{LHS≠RHS}$

Substituting $p=11$in the given equation, we get

$\Rightarrow 11+6\ne 5$

$\Rightarrow 17\ne 5$

So, $\text{LHS≠RHS}$

Substituting $p=30$in the given equation, we get

$\Rightarrow 30+6\ne 5$

$\Rightarrow 36\ne 5$

So, $\text{LHS≠RHS}$

Hence, the correct option is $\text{A}$
