Answer 2

Answer:

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.
