Question 862582
If X+Z=48, 48-X=Z
Let X = X
Let 48-X = Z
As X is 6 less than Y, Let Y = X+6
 
X <b>is</b> 12 more than Z
{{{X=Z+12}}}
Substitute 48-X for Z
{{{X=48-X+12}}}
Add 48 and 12
{{{X=60-X}}}
Add X to both sides
{{{2X=60}}}
Divide both sides by  2
{{{X=30}}}
48-X=Z
48-30=Z
18=Z
 
X+6=Y
30+6=Y
36=Y
 
<h3>The Numbers X, Y, and Z are 30, 36, and 18, respectively</h3>
