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

Answer:
0 mph
Step-by-step explanation:
The slope of the curve in section B is ...
m = (y2 -y1)/(x2 -x1)
m = (30 mi - 30 mi)/(6 h -4 h) = (0 mi)(2 h) = 0 mi/h
The rate of change in section B is 0 miles per hour.
Box 2 I believe is correct because 3 x 1 x 2 is 6.
Cross multiply
5(b3-2) = 2(3b2 - 2b2 -5)
5b3 - 10 = 6b3 - 4b2 - 10
5b3 = 6b3 - 4b2
0 = b3 - 4b2
0 = b2(b - 4)
b2 = 0 —> b = 0
b-4=0 —> b = 4
