Answer:

(3,1)

Step-by-step explanation:

5x + 2y = 17

3x - 2y = 7

Add the two equations to eliminate y

5x + 2y = 17

3x - 2y = 7

---------------------

8x = 24

Divide each side by 8

8x/8 = 24/8

x =3

Now we need to find y

5x+2y = 17

5(3) +2y =17

15+2y =17

Subtract 15 from each side

15-15+2y =17-15

2y =2

Divide each side yby2

2y/2 =2/2

y=1

liraira [26]

Answer:

39 cups

Step-by-step explanation:

If we assume that the 3.5 cups of concentrate make 3.5+3 = 6.5 cups of tea, we can use the proportion ...

6.5/3.5 = x/21

to find the x cups of tea Ahab can make with 21 cups of concentrate.

Multiplying by 21, we get ...

x = 21(6.5/3.5) = 39

Ahab can make 39 cups of tea.
