Answer:
5.25
Step-by-step explanation:
27 = 8a - 15
We have to find "a" here.
We add 15 to each side. The 15 cancels out on the left, and we are left with 27+15 = 42. We then have to divide by 8 on each side to get the "a" by itself.
42/8 = 5.25. We can check our work by answering the "number" with the word problem. 8 * 5.25 = 42 and then 42-15 = 27. Our number gets the answer 27, therefore the answer is 5.25!
Hope this helps.
