Use the substitution method:
2x - 6y = -12
x - 2y = -8
Then x = 2y - 8
Substitute in the first equation:
2(2y - 8) - 6y = -12
4y - 16 - 6y = -12
-2y = 4
y = -2
Now substitute y in one of the two equations given you prefer:
For example x-2*(-2) = -8
x + 4 = -8
x = -12
The solutions are x = -12 and y = -2

finlep [7]

Answer:

The answer to your question is: # of times = 60.7

Step-by-step explanation:

data

7.4 billion people

each person occupied 13 inches

Earth circumference = 25000 miles

length of the lines = 13 in x 7.4 billion people

                               = 13 x 7 400 000 000

                              = 9.62 x 10 ¹⁰ in

Convert in to miles

                     1 mile  --------------- 63360 in

                     x mi     ---------------  9.62 x 10 ¹⁰  in

     x = 1518308.1 mi

Now divide, the line of people by the circumference

         # of times =  1518308.1 mi /  25000 mi = 60.7
