If: 7x+11y+13z = 15
Then: 7(15/21)+11(15/33)+13(15/39) = 15 because 5+5+5 =15
So it follows: 7(15/21)*11(15/33)*13(15/39) = 125 because 5*5*5 = 125
Therefore: x = 15/21 y = 15/33 and z = 15/39
Or as: x = 5/7 y = 5/11 and z = 5/13

What are the values of the variables when the equal terms of 3x plus 5y plus 7z have a sum of 357 showing work?
If 3x, 5y and 7z are equal terms, them each of them will equal one third of 357, or 119. 3x = 119 x = 39 and 2/3 5y = 119 y = 23 and 4/5 7z = 119 z = 17
