Question 654600: Hi! I need some help. Sorry for the trouble. My question is:
A number is four times another number. Six times the smaller number plus half of the larger number equals 212. Find the numbers.
I tried to solve it myself but I couldn't. I thought that since the larger number is four times the smaller number, and six times the smaller number plus half the larger equals 212, then 8 times the smaller number would be 212. So the smaller number is 26.5. This means that the larger number is 106. Half of 106 is 53. 26.5 times 6 is 159. 159 plus 53 is 212. But, for some reason, my answers don't match the answer key at the back of my book. Am I doing something wrong? And if so, what?
Thank you in advance, whoever you are for reading this problem and trying to solve it!

Hi,
Best to Set it Up and Solve it Algebraicly
A numberhighlight%28y%29 is four times another numberhighlight%28x%29.
Six times the smaller number plus half of the larger number equals 212
Question states***
6x+%2B+y%2F2+=+212 || y+=+4x, Substituting for y...
6x+%2B+4x%2F2+=+212
6x+%2B+2x+=+212
8x+=+212
x = 212/8 = 26.5 and y = 106
and...
6%2A26.5+%2B+53+=+159+%2B+53+=++212
