Question

if x = 1/2y, y = 1/4 and z = 9 find the value of 8z + 2x -y​

Answer 1

Step-by-step explanation:

Given equation :

8z + 2x - y

Given values :

x = ½

y = ¼

z = 9

Substitution of the values :

$= 8z + 2x - y \\ =( 8 \times \frac{1}{2} ) +2 \times \frac{1}{2} - 9 \\ = 4 + 1 - 9 \\ = - 4 \: ans.$
