Avoid would be the best answer for this
I would say that planking would contract most of your muscles, and maybe the wall sit too.
You have the equation:
4(6x-20)= 88
You first distribute the 4 to the 6x and to the -20:
Now you equation looks like this:
20x-80=88
Now you combine 80 with 88 and get 168:
And now you have 20x=168
You divide 20 by 20 and 168 by 20 and get:
x = 8.4
Hope this helps! Have a good day!
If that was a true/false question, it is true.
