Answer:

<u>The value of x is 5 & y is 0.</u>

Step-by-step explanation:

x - y = 5

x = 5 + y -----------> (1)

3x + 2y = 15

By substituting the value of 'x' from (1)

3 (5 + y) + 2y = 15

15 + 3y + 2y = 15

3y + 2y = 15 - 15

5y = 0

y = 0/5

<u>y = 0</u>

So, in (1)

x = 5 + y

x = 5 + (0)

<u>x = 5</u>

<u>•°• The value of x is 5 & y is 0.</u>

Method used:

  • Substitution method.

Harrison can purchase 4 dvds for $19.99 or 6 dvds for $22.50 which is the better deal?
adelina 88 [10]

$19.99 x 4 = $79.96

$22.50 x 6 = $135

$19.99 x 6 = $119.94

$22.50 x 4 = $90

The best answer to this choice is 4 dvds for $19.99. why?, because if it was 6 or 4 dvds for $19.99 the price would be more inexpensive then the price for $22.50, because if it was 22.50 x 4 or 6 dvds the price would be more expensive.
