​

Answer 1

Answer:

Here, the answer is 25

Step-by-step explanation:

Here, As given in question,

=x=6, y=(-2), z=1

Now, by putting the values of x, y, z, in the equation, we get,

=3×(6)-4(-2)-1=25

=18-(-8)-1=25

=18+8-1=25 [Minus becomes plus when multiplied with minus, e.g.= -×(-)=+ ]

=26-1=25

=25=25
