Question

IF X= -3, y= -1, z = 0 THAN VALUE OF (x+y-7z)?​

Answer 1

substitute the values,

-3+-1-7*0

-3+-1

ans=-4

Answer 2

The value of  (x+y-7z) is -4.

Step-by-step explanation:

• We are given ,

$x=-3$

$y=-1$

$z=0$

• Calculation for the value of given expression,

We have to find the value of $(x+y-7*z)$ and we have the values of x, y and z with us then by simply substitution of x, y and z we get our answer.

By substituting the $x,y, z$ we get,

$(x+y-7*z)$  = $(-3)+(-1)-7*(0)$

                      $= -3-1-0$

                       $= -4$

So the value of given expression is - 4.
