20%2F%282x%2B3%29+=+%2817x%29%2F%282x%2B3%29+-5 Start with the given equation


Multiply EVERY term by the LCD 2x%2B3 to clear out the fractions.


20=17x-5%282x%2B3%29 Simplify


20=17x-10x-15 Distribute


20%2B15=17x-10x Add 15 to both sides


35=7x Combine like terms.


35%2F7=x Divide both sides by 7 to isolate x.


5=x Divide


=========================================

Answer:

So the solution is x=5
