Elimination Method:
5x - 4y = 6
-5x + 4y = -10
5x - 4y = 6
+ -5x + 4y = -10
————————-
0 = -4
This statement is false, so there is no solution to the system of equations.
The answer you are looking for is 3.
To find this, you must first distribute the 3 into the parenthesis. 3 x 9 = 27 and 3 x 4 = 12.
Next, you subtract 12 from 27. 27 - 12 = 15.
Finally, divide 15 by 5 to get your final answer as 3.
I hope this helps!

Answer:
Each oven is discounted by $20.
Step-by-step explanation:
Original price of oven in dollars = 
To find total cost for 9 such ovens without discount we will apply unitary method.
If 1 oven costs in dollars = 
Then 9 ovens will cost in dollars = 
The ovens are purchased by a restaurant supplier at some discounted price.
The new price after discount in dollars = 
We see that the total cost of 9 ovens which was originally
has been decreased to
after discount.
The decrease amount is the discount amount on 9 ovens which is = $180
To find discount offered on each oven, we will again use unitary method.
Discount on 9 ovens = $180
∴ Discount on 1 oven = 
∴ Each oven is discounted by $20.
