Answer 1

Answer:

19 is correct answer

Step-by-step explanation:

x=1, y=2 and z=5

=3x-2y+4z

=3×1-2×2+4×5

=3-4+20

=23-4

=19

Answer 2

$\bold\red{Answer:}$

Given value of x = 1, y = 2 and z = 5

To find :

$3x - 2y + 4z$

Putting values of x,y and z

$(3 \times 1) - (2 \times 2 )+ (4 \times 5)$

$3 - 4 + 20$

$23 - 4$

$19$

Hence, 3x - 2y + 4z = 19
