Question

Find the value of z if 2 + 3 (z-2) = 8.

Answer 1

$\huge \sf Solution :$

$\sf 2 + 3(z-2) = 8$

$\sf 2 + 3z - 6 = 8$

$\sf 3z - 4 = 8$

$\sf 3z = 8 + 4$

$\sf 3z = 12$

$\sf z = \dfrac{12}{3}$

$\sf z = \dfrac{\cancel{12}^{4}}{\cancel{3}}$

$\boxed{\sf z = 4}$

$\color{fuchsia} \sf \therefore \: value \: of \: z = 4$

Answer 2

Answer:

2+3z-6=8

3z-4=8

3z=12

z=12/3

z=4
