Solution

Answer: 3

Solution:

Given, $7 x + 4 = 25$

Subtracting 4 from both sides of the equation we get,

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

$\Rightarrow$ $7 x = 21$

Dividing both sides of this equation by 7, we get

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

$\Rightarrow x = 3$
