Answer:

(-6,17)

Step-by-step explanation:

-2x-y=-5,

 3x+y=-1

Add the two equations together to eliminate t

-2x-y=-5

 3x+y=-1

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

x      = -6

Now that we know x, we can substitute it into one equation to find y

3x+y = 1

3(-6) +y = 1

-18 +y = -1

Add 18 to each side

-18+18 +y = -1+18

y = 17

(-6,17)

Mazyrski [523]

Answer:

12.5 inches of gold chain.

Step-by-step explanation:

To get the remaining chain of gold we need to calculate

8/8 - 3/8 = 5/8 of 20 inches

then multiply:

20 * 5/8 =  100/8

100/8 = 12.5 inches
