Question

If $10+x$ is $5$ more than $10$, what is the value of $2x$ ?

• A. $-5$
• B. $5$
• C. $10$
• D. $25$

Answer 1

The correct option is C $10$

Given that

$10$ $+$ $x$ is $5$ more than $10$

Formally, we can express this

$10$ $+$ $x$ $=$ $10$ $+$ $5$

$\Rightarrow x$ $=$ $15$ $-$ $10$

$\Rightarrow x$ $=$ $5$

To find $2x$,

$2x$ $=$ $2$ $\times$ $x$

$=$ $2$ $\times$ $5$

$=$ $10$

Therefore, the value of ${}^{\prime }2x^{\prime }$ is ${}^{\prime }{10}^{\prime }$.
