Question

What is the value of 3-6(z-2) if z=-2

Answer 1

Given :

• z = - 2

To Find :

• 3 - 6(z - 2) = ?

Solution :

By substituting value of z = - 2 in 3 - 6(z - 2), we get :

$\tt : \implies 3 - 6(z - 2) = 3 - 6((-2) - 2)$

$\tt : \implies 3 - 6(z - 2) = 3 - 6(-2 - 2)$

$\tt : \implies 3 - 6(z - 2) = 3 - 6(- 4)$

$\tt : \implies 3 - 6(z - 2) = 3 + 24$

$\tt : \implies 3 - 6(z - 2) = 27$

$\large \underline{\boxed{\bf{ 3 - 6(z - 2) = 27}}}$

Hence, value of 3 - 6(z - 2) = 27.
