Y= 5x+9, y=8x-6 find x and y

x= 5, y= 34

Step-by-step explanation:

y= 5x +9 (1)

y= 8x -6 (2)

Substitute (1) into (2):

5x +9= 8x -6

Bring x terms to one side, constants to the other:

8x -5x= 9 +6

3x= 15

Divide both sides by 3:

x= 15 ÷3

x= 5

Substitute x= 5 into (1):

y= 5(5) +9

y= 25 +9

y= 34

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
