Question

if X + Y + Z = 56 ; y +z =29 then find x​

Answer 1

hope this answer will be helpful ^_^

Answer 2

Answer:

x+y+z = 56

So, this is the same as

x + (y+z) = 56

This is due to the essential associative nature of linear equations in any finite number of independent variables occuring in the same equation

So,

x = 56 - (y+z) = 56-29 = 27

Hope this helps you !
