Given:

Value of n- 10 (a)

Value of n- 2 (b)

Calculation:

(a) n-9 = 19

=> 10-9 = 19

=> 19 = 10+9

=> 19= 19

(b)17×2+5 = 25

=> 17×2+5 = 25

=> 34+5 = 25

=> 25 = 34-5

Answer 2

$\sf{{\underline{\boxed{\sf{\pmb{ (α) n-9 = 19 }}}}}}$

$\sf\implies{ 10-9 = 19}$

$\sf\implies{ 19 = 10+9}$

$\sf\implies{ 19= 19 }$

$\sf{{\underline{\boxed{\sf{\pmb{(ϐ)17×2+5 =25}}}}}}$

$\sf\implies{ 17×2+5 = 25}$

$\sf\implies{ 34+5 = 25}$

$\sf\implies{25 = 34-5 }$
