Question

$x = 10 \: \ \\ y = 0 \\ z = 5$
Find the value of x + y - 2z​

Answer 1

10 + 0 - 10 is equal to zero

Answer 2

Given

• x = 10
• y = 0
• z = 5

To find

• value of x+y-2z

Solution

↦ x + y - 2z

substituting the given values

↦ 10 + 0 - 2 × 5

↦ 10 + 0 - 10

↦ x + y - 2z = 0

★ Hence, the required value is 0 (zero)
