Question

27x +28y+ 29z=363. find the value of X +y+z ?​

Answer 1

Given:

27x + 28y + 29z = 363.  

To find:

Find the value of X + y + z ?​

Solution:

From given, we have,

27x + 28y + 29z = 363.  

here we use the trial and error method.

27(5) + 28 (4) + 29 (4) = 363.  

135 + 112 + 116 = 363

363 = 363

Therefore, the values of x, y and z are 5, 4 and 4 respectively.

The value of x + y + z = 5 + 4 + 4 = 13

Therefore, the value of x + y + z is 13
