Question

x+y=10 y+z=20 z+x=24 whats the valuve of x ,y and z

Answer 1

Hey

Here is your answer,

X+y=10
--------------eq.1
X=10-y

Y+z=20
--------------eq.2
Z=20-y

Z+x=24
-------------eq.3
Substitute the values in equation 3,
20-y+10-y=24
30-2y=24
-2y=24-30
-2y=-6
y=3

X=10-y
=10-3
=7

Z=20-y
=20-3
=17

Hope it helps you!

Answer 2

Given That
x+y=10 , y+z=20 And z+x=24
Substitute The Value Of y=10-x In y+z=20
Then
10-x+z=20 => z-x=10
Solve z-x=10 And z+x=24
then 2z=34
z=17
Then Substitute The Value Of z=17 in y+z=20 And In z+x=24
then y=3,x=7
The Required Values Are x=7,y=3 And z=17
