Ineed confirmation to this. i did it already. i just want to know if i’m right. work it out for me to see.

(a)

4x + 3y = 23

5x + 2y = 20

(b)

4x + 3y = 23   ⇒   -2(4x + 3y = 23)   ⇒    -8x - 6y = -46

5x + 2y = 20   ⇒    3(5x + 2y = 20)   ⇒   15x + 6y = 60

                                                                 7x          = 14

                                                                   x          = 2

5x + 2y = 20

5(2) + 2y = 20

 10 + 2y = 20

        2y = 10

         y = 5

biscuit = $2, ice cream = $5

step-by-step explanation:

no of data

divide by no of mode
