Answer 1

Answer:

(y+yx+2x)/(1+x)(1-x)

Step-by-step explanation:

To add two fractions you have to find the common denominator. In this case, the easiest denominator that both fractions share is (1-x)(1+x). So now, the fractions become

(x+y)(1+x)/(1-x)(1+x) + x(1-x)/(1+x)(1-x)      Note: we have to multiply by the same thing on both numerator and denominator.

Simplifying gives us (x+y)(1+x) + x(1-x) all over (1-x)(1+x). Lastly, expand and combine which will give you (y+yx+2x)/(1+x)(1-x)
