Question

1. Stiind ca x+y+z+11=43, determinati valoarea lui x+y+z.

2. Daca 3·x+4·y+5·z+27=59, determinati 5·z+3·x+4·y.

Answer 1

1. x+y+z+11=43
   x+y+z=43-11
   x+y+z=32

2. 3x+4y+5z+27=59
    5z+4y+3x=59-27
    5z+4y+3x=32

Answer 2

1)x+y+z+11=43
   x+y+z=43-11
   x+y+z=32

2)3x+4y+5z+27=59
   5z+3x+4y=59-27
   5z+3x+4y=32
