Answer:

Multiply by 3 -> 3(x - y = 6)

Step-by-step explanation:

Cuz since the 2nd is positive 3y

u need a negative 3y to get rid of it

3(x - y = 6)

2x + 3y = 7

3x - 3y = 18

2x + 3y = 7

5x/5 = 25/5

x = 5

5 - y = 6

-5 -5

-y/-1= 1/-1

y = -1

(5,-1)

The price of the potatoes per pound at grocery mart is $(\$0.60-\$0.57)=\$0.03$ less than the price at Baldwin Hills market.
