Option A
Answer: 
The Value of 2(x + y) – (x – z) is 1, if x = 2, y = 1, and z = –3 
Solution: 
Given Data: 
Given values are x = 2, y = 1, and z = –3 
we have to find the value of above equation
Let the given function is 2(x + y) – (x – z) 
Substitute the value of x = 2, y = 1 and z = -3 in the above equation. 
2(x + y) – (x – z) = 2(2+ 1) – (2 – (-3)) 
= 2(3) – (2+3) 
= 2(3)-(5) 
= 6-5 = 1 
Hence the value of 2(x + y) – (x – z) is 1.
