Answer 2

Answer:

x = 500

y = 50

Step-by-step explanation:

7x + 6y = 3800  ---- (1)

3x + 5y = 1750 ---- (2)

(1) x 3 => 21x + 18y = 11 400

(2) x 7 => 21x + 35y = 12 250

          - - - - - - - - - - - - - - - - - - - -

                        -17y = -850

                             y = 50

3x + 5y = 1750

3x + 5.50 = 1750

3x = 1750 - 250

x = 1500 : 3

x = 500
