harry had $32. he spent all the money buying three notebooks for x dollars each and four packs of index cards for y dollars each. if harry had bought five notebooks and five packs of index cards, he would have run short by $18. the following system of equations models this scenario:

3x + 4y = 32
5x + 5y = 50

use the system of equations to solve for x and y.

x = 8

y = 2

Step-by-step explanation:

Given that:

3x + 4y = 32   eq1

5x + 5y = 50 eq2

From taking 5 common from eq2:

x + y = 10

Or it can also be written as:

x = 10 - y eq3

Now put this value of x in eq1

3(10 - y) + 4y = 32

By simplifying:

30 - 3y +4y= 32

30 +y = 32

Subtracting 30 from both sides:

y = 32 - 30

y = 2

Putting value of y in eq 3

x = 10 - 2

x = 8
