X=price of a hot dogy=price of a soft drinkWe can suggest the following system of equations: 6x+4y=133x+4y=8.50 We solve this system of equations by reduction method. 6x+4y=13-(3x+4y=8.5)------------------------ 3x=4.5 ⇒x=4.5/3=1.5 Answer: the price of a hot dog will be $1.5.
If you want to know the price of a soft drink, you have to find "y".6x+4y=13 6(1.5)+4y=139+4y=134y=13-94y=4y=4/4y=1 The price of a soft drink is $1. Hope this helps! :)
Y0ou find a common denominatior, in this case is 15.... then multiply whatever u had to get the denominator 15 times the top number, so 3/5 + 10/15 = 13/15
