Question

x + y + xy = 29 Y+z+Yz = 41
z+x+xz= 34 then find 3z-4x+5y = ?​

Answer 1

3×6-4×4+5×5= 27?????

I think I'm right coz' after thinking a lot I found the values which completely fits to all the 3 conditions given by you ...

as x=4 , y=5 and z=6

so, in the first case, 5+4+5×4=9+20=29

in the second case, 5+6+5×6= 11+30=41

in the 3rd case = 6+4+6×4=10+24=34

therefore.....

x=4, y=5 and z=6

therefore my answer is correct dear....

may you have a great life...
