The product of 7 and a number, increased by 3, is equal to twice the number, subtracted from 39.

7X + 3 = 39 - 2X

Now we collect the terms and find
9X = 36

Finally we divide by 9
X = 4

So our answer is 4

Law Incorporation [45]

Hello there!

To find the fraction of applicants that are accepted into the Ivy League college, all you have to do is put the number of students accepted (numerator) over the total number of students that apply (denominator). This makes the fraction 5/100. This fraction can be simplified. To simplified, find the GCF of the two numbers. The GCF of 5 and 100 is 5. Divide both parts by 5. 5/100 ÷ 5/5 is 1/20. There. 5/100 is 1/20 in simplest form. The Ivy League college accepts 1/20 of it's applicants.
