Answer 2

Given:

• 8(z + 4) = 40

To Find:

• The value of z = ?

Solution:

Now,solve the value of z.

$\: \: \: \: \: \sf \leadsto \: 8(z + 4) = 40 \\ \\ \: \: \: \: \: \sf \leadsto \: 8z + 32 = 40 \\ \\ \: \: \: \: \: \sf \leadsto \: 8z = 40 - 32 \\ \\ \: \: \: \: \: \sf \leadsto \: 8z = 8 \\ \\ \: \: \: \: \: \sf \leadsto \: z = 1$

Therefore, The value of z is 1.

Now, Prove:

$\: \: \: \: \sf \leadsto \: 8(z + 4) = 40 \\ \\ \: \: \: \: \sf \leadsto \: 8(1 + 4) = 40 \\ \\ \: \: \: \: \sf \leadsto \: 8 + 32 = 40 \\ \\ \: \: \: \: \sf \: 40 = 40$

●LHS = RHS

Hence, Proved
