Question: strikethrough text on math

Hello Forum, 

I have a quick question i was hoping someone could help me with. 

Is there a way to put a line though "math" text like below

2*5+8 = 2*5+8

to visualize that to values cancels each other out? 

I hope someone can help, i can´t find anything on google

Thanks in advance
