Problem 1101

When algebraic fractions are combined, sometimes the answer needs to be factored in order to reduce it to lowest terms. x2xyy2xy=x2y2xy=(x+y)(xy)(xy)=x+y\frac{x^2}{x-y} - \frac{y^2}{x-y} = \frac{x^2 - y^2}{x-y} = \frac{(x+y)(x-y)}{(x-y)} = x+y 5a+3b2+ab2=5a+3b+ab2=6a+2b2=2(3a+b)2=3a+b\frac{5a+3b}{2} + \frac{a-b}{2} = \frac{5a+3b+a-b}{2} = \frac{6a+2b}{2} = \frac{2(3a+b)}{2} = 3a+b
Combine the following. The answers will need to be factored in order to reduce them to lowest terms.

Problem 1176

If a certain number is added to the denominator of the fraction 35\frac{3}{5} and 7 is added to the numerator, the result is a fraction that will reduce to 12\frac{1}{2}. What number is added to the denominator?
Let x=x= the number added to the denominator. 3+75+x=12\frac{3+7}{5+x}=\frac{1}{2}
