$\huge\color{cyan}\boxed{\colorbox{black}{☛Solution࿐}}$

⟶ Let the price of 1Glove be ' x '

⟶ Let the price of 1 mask be 'y'

⟶ From the question,

⟶ Price of  3gloves and 8 masks is ₹ 390 and the price of 7gloves and 4masks is ₹ 470 .

⟶ 3x+3y=390

⟶ 7x+4y=470

⟶ 7(3x+4y = 390)

⟶ 3( 7x+4y=470)

⟶ 21x+28y = 2730 -

⟶ 21x+12y = 1410

__________________________________

16y = 1320

y = 1320÷ 16

y = 82.5

⟶ when y =82.5

__________________________________

⟶ 3x+ 3y = 390

⟶ 3x+ 3×82.5 = 390

⟶ 3x+ 247.5 = 390

⟶ 3x = 390 - 247.5

⟶ 3x = -208.5

⟶ x = - 208.5 ÷ 3

⟶ x = - 69.5

__________________________________

⟶ price of 1 glove =x = -69.5 rupees

⟶ price of 1 mask = y = 82.5 rupees.
