First of all you need to push the restrictions for x so x not can being never equal 4 and -7 because than these denominators will be equal zero and these fractions undefined
1/(x-4) = 2/(x+7) cross multiple and will get
x+7 = 2(x-4)
x+7=2x-8
x = 15

<span>So we want to know the number of teachers the university should have if the ratio of students to teachers is 14:1 and the number of students is 896. If x is the number of teachers: 14/1=896/x. Now we solve for x: Lets multiply both sides with x: x*(14/1)=896 and divide both sides by 14 and we get: x=896/14 and x=64. So the university should have 64 teachers.</span>
