1. What is the value of "y" for the given value of x and z
y= x +z x=3 z=15
Substituting x=5 and z=15 into the expression for y, we obtain
y=x+z=5+15=20
So y=20.

2. Rewrite each fraction with the Lowest Common Denominator
4/15, 2/9, 3/5 43/36 + 3/5 + 1/4
The lowest common denominator for the first three fractions is 45. So we ...

#### Solution Summary

Lowest Common Denominator is ascertained. The value of y for the given value of x and z are determined.
