You purchased 8 gal of paint and 3 brushes for 152.5. the next day, you purchased 6 gal of paint and 2 brushes for 113. how much does each gallon of paint and each brush

Let the price of paint be x and the price of brush be y

8x + 3y = 152.5 (1)
6x + 2y = 113 (2)

(1) x 2 :
16x + 6y =305 (1a)

(2) x (3) :
18x + 6y = 339 (2a)

(2a) - (1a) :
2x = 34
x = 17 sub into (2)
6(17) + 2y = 113
102 + 2y = 113
2y = 113 - 102
2y = 11
y = 5.5

x = $17, y = $5.50

Each gallon of paint costs $17 and each brush costs $5.50

What are the following algebraic equations. you need to post those if you want the answer
