Question

2x - 3y + 6z (x = -1 y=. 2 z = -3
​

Answer 1

Step-by-step explanation:

2x - 3y + 6z

given (x = -1, y = 2, z = -3)

= 2(-1)-3(2)+6(-3)

= -2-6-18

= -26

hope it is helpful to you

Answer 2

Answer:

$2x - 3y + 6z$

$we \: know \: that \:( x = - 1 )\:( y = 2 )\: (z = - 3)$

$(2 \times (- 1)) - (3 \times 2) + (6 \times (- 3))$

$( - 2) - 6 + ( - 18)$

$- 2 - 6 - 18$

$- 26$
