Answer:
5/19
Step-by-step explanation:
There's no explanation, it's just common sense ♀️
5x - 3y = 11 ⇒ 5x - 3y = 11 ⇒ 5x - 3y = 11
x - 2y = 2 ⇒ -5(x - 3y) = 2 ⇒ <u>-5x + 15y = 2</u>
<u>12y</u> = <u>13</u>
12 12
y = 1 1/12
5x - 3(1 1/12) = 11
5x - 3 1/4 = 11
<u> +3 1/4 +3 1/4</u>
<u> 5x</u> = <u>14 1/4</u>
5 5
x = 2 17/20
(x, y) = (2 17/20, 1 1/12)

Answer:
The total amount of money Alex spends on 5 DVD = $ 35.
Step-by-step explanation:
Total number of DVD purchased by Alex = 5
The cost of each DVD = $9
So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)
= 5 x ( $ 9) = $ 45
Now , the discount if 1 DVD = $ 2
So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)
= 5 x ($ 2) = $ 10
⇒ The total amount Alex spends
= Total cost of 5 DVD - Discount on 5 DVD
= $ 45 - $ 10 = $ 35
Hence, the total amount of money Alex spends on 5 DVD = $ 35.
