Answer:
a=72
Step-by-step explanation:
When you get an equation like this, it is saying that A is being divided by 4 and that would equal 18.
If you simply move the 4 to the other side of the equation by multiplying 18 by the 4, it will give you 72: a=72.
You can check your work by seeing if 72(A) divided by 4 is really equivalent to 18. Plugging 72/4 into the calculator will give you 18.
