Question 27

If $7x+4=25$, then the value of $x$ is ___ .

Answer 1

Answer: 3

Solution:

Given, $7x+4=25$

Subtracting 4 from both sides of the equation we get,

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

$\Rightarrow$ $7x=21$

Dividing both sides of this equation by 7, we get

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

$\Rightarrow x=3$
