Total pounds of 2.5 pounds of raspberries and 2 pounds of kiwi bought is 4.5 pounds.
Total pounds of 2 pounds of raspberries and y pounds of kiwi is (2 +y) pounds.
In order to determine the total pounds of fruits Ellie buys, the pounds of raspberries bought would be added to the pounds of Kiwi she bought.
Addition is the process of determining the total value of two or more numbers by adding the numbers together. It is one of the basic mathematical operations.
Total pounds Ellie bought when she buys 2.5 pounds of raspberries and 2 pounds of kiwi: 2.5 + 2 = 4.5 pounds.
Total pounds Ellie bought when she buys 2 pounds of raspberries and y pounds of kiwi: 2 + y = (2 +y) pounds.

Answer:
<h2><u>
X= 1</u></h2>
Step-by-step explanation:
<em>y = 5 - 3x</em>
<em>5x - 4y = -3</em>
you substitute for y since you know what y equals.
so, it will then be
5x -4(5 -3x) = -3
you then multiply -4 by everything in the parenthesis
so then it will be
5x - 20 + 12x = -3
Then combine like terms
5x + 12x = 17x
then the new equation is
17x -20 = -3
the next step is to and 20 to both sides since it is negative you do the opposite.
17x - 20 = -3
<u> + 20 +20</u>
17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.
<h2><u>
so, X = 1</u></h2>
