Answer: No
Step-by-step explanation:
Data: x+14<20
x=9? Is what your trying to find
<u>Step one, Isolate x by subtracting 14 on both sides</u>
X+14-14<20-14=X=6
Reason: Since you are trying to find if x=9, you have to isolate it. The way to do that is to get rid of +14 by subtracting it by 14. However, since what you do to one side you do to the other, you subtract +20 by 14 to get 6.
Since x=6 isn't x=9, the answer is No
Answer: No
I hope this helps!
