Question

If $7x+4=25$, then $x$ is equal to:

• A. $\frac{29}{7}$
• B. $\frac{100}{7}$
• C. $2$
• D. $3$

Answer 1

The correct option is D

$3$

Find the value of $x$

Given, $7x+4=25$

Subtracting both the sides of the given equation by $4$, we get,

$\Rightarrow 7x+4-4=25-4$

$\Rightarrow 7x=21$

$\Rightarrow x=\frac{21}{7}$

$\Rightarrow x=3$

Hence, the value of $x$ is $3$, so, option (D) is correct.
