To find the original price, add the discount back onto the sales price.
17.55+5.85= 23.4

Solve the equation below.<br> 3(17x – 6.5) = 108
olga_2 [115]

Answer:

x=2.5

Step-by-step explanation:

3(17x – 6.5) = 108

Divide each side by 3

3/3(17x – 6.5) = 108/3

17x - 6.5 =36

Add 6.5 to each side

17x -6.5+6.5=36+6.5

17x = 42.5

Divide each side by 17

17x/17 = 42.5/17

x = 2.5
