Solve for z. 7-~-3z+2=4 What is the root? If there is no root, choose none.

Desmos is Function Calculator is a great tool for this, the correct answer is z = 7/3

7/3 = 2.333~ and so √ (3*2.333~) + 2 = 2.9999999833333~

Now 7 - 2.9999999833333~ = 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little werid, just plug (7/3) in for z and you will get 4, trust me

The answer is none, I believe
