Please it is very urgent

Substitute x = -1 , y = -2 , z = 3 in each expression and find it's value

a) -20x + 4y + 12z

b) -x -y -z ​​

Answer 1

Answer:

Very simple

Step-by-step explanation:

a) x=-1. y=-2. z=3.

-20(-1) + 4(-2) +12(3)= 20 - 8 + 36

solve it

$Given~values~of~x,y~and~z~are~:$

$x = -1,~y = -2,~z = 3$

$\large\tt{a) \: -20x+4y+12z}$

$\large\implies\tt\blue{-20(-1)+4(-2)+12(3)}$

$:\large\implies\tt\blue{48}$

$\large\tt{b) \: -x-y-z}$

$\large\implies\tt\blue{-(-1)-(-2)-(3)}$

$:\large\implies\tt\blue{0}$
