Answer 1

X+Y+Z=9---------(equation-1)

X+Z=5------------(eq.2)

Y+Z=7-------------(eq.3)

According to equation 2nd-

X+Z=5

X=5-Z

According to equation 3rd-

Y+Z=7

Y=7-Z

Put the value of X and Y in equation 1st-

5-Z+7-Z+Z=9

12-2Z+Z=9

-2Z+Z=9-12

-Z= -3

Z=3

put the value of Z in equation 2nd and 3rd-

X+Z=5

X+3=5

X=5-3

X=2.........

and

Y+Z=7

Y+3=7

Y=7-3

Y=4.............

So,

X=2

Y=4

Z=3.
