Question

simplify and evaluate 4{3x+2y-3z} if x=1, y=-2, z=3​

Answer 1

Answer:

-40

Step-by-step explanation:

4{3x+2y-3z} if x=1,y=-2,z=3

=4{3×1+2×(-2)-3×3}

=4{3+(-4)-9}

=4{3-4-9}

=4{3-13}

=4×{-10}

=-40

Answer 2

Answer:

Given, x = 1 , y = -2 , z = 3

so

$4(3x + 2y - 3z) \\ \\ = 12x + 8y - 12z \\ \\ = 12(1) + 8( - 2) - 12(3) \\ \\ = 12 + ( - 16) - 36 \\ \\ = 12 - 16 - 36 \\ \\ = - 4 - 36 \\ \\ = - 40$

hope it helps :)
