Question 335132: Problem is solving for X. (rational equation)
There should be a line under each one (between x+4 and x+5 and then another between x-2 and x+4) with ONE equal sign.
x+4 = x-2
x+5 = x+4
Thanks in advance!

I presume you mean the following:
If you cross multiply, you get:
If you multiply these out, you will get:
If you subtract the expression on the right side of the equation from both sides of the equation, then you will get:
When you combine like terms, you will get:
If you subtract 26 from both sides of this equation, you will get:
If you divide both sides of this equation by 5, you will get:
x = -26/5
That should be your answer.
Substitute for x in your original equation to see if it comes out true.
You start with .
Since -26/5 = -5.2, then you replace x with -5.2 to get:
.
This becomes:
which becomes:
which is true, confirming that your answer of x = -26/5 = -5.2 is correct.
