-10y + 9x = - 9....A
10y + 5x = - 5.....B

You should see right away that -10y and 10y cancel out.

We are left with

14x = -14

x = -14/14

x = -1

Plug x = -1 into EITHER equation A or B to find y.

I will use equation A.

-10y + 9(-1) = - 9

-10y - 9 = - 9

-10y = - 9 + 9

- 10y = 0

y = 0/-10

y = 0

Done!

What are the steps to converting 86,000cm to km
yarga [219]
100 cm = 1 m => 1 cm = 1/100 m so, 86000 cm = 86000 * (1/100) m = 86000/100 m = 860 m now, 1000 m = 1 km => 1 m = 1/1000 km so, 860 m = 860 * (1/1000) km = 860/1000 km = 0.86 km so, 86000 cm = 0.86 km
