Answer 2

Hello, there!

5x + 4 = 19

Answer: 3
-------------------------------------------------------------------------------------------------------

Explanation:


To solve this, we will do the following:

We want to isolate the x. This means that we want x to be on one side by itself

To do this, we will subtract 4 from each side to keep 5x by itself on the left side. We must subtract 4 from each side because whatever you do to one side, you must do to the other side. This way, the value of the equation will still stay the same.

5x + 4 = 19
      -4      -4

5x = 15

We now have 5x = 15

Now, we want to simplify this wequation. 

What is the greatest common actor of 5x and 15? 

The GCF of 5x and 15 is 5

So, we must divide each side by 5 to get our final answer

 $\frac{5x}{5} = \frac{15}{5}$

x = 3

So, our final answer is x = 3
