Question:

Solution:

According to the picture, we obtain the following equation:

$7x-20\text{ = 3x}$

this is equivalent to:

$7x-3x\text{ = 20}$

this is equivalent to:

$4x\text{ = 20}$

solving for x, we obtain:

$x\text{ = }(20)/(4)=5$

So that, we can conclude that the correct answer is:

$x\text{ = 5}$
