Answer:
You have to eliminate one of the variables when the equations are added.
A) x + 2y + z = 10
B) 2x -y +3z = -5
C) 2x -3y -5z = 27
We mulutiply A) by 2 then add it to B and C
A) 2x + 4y + 2z = 20 and the sum =
6x = 42 Luckily, the "y" and "z" variables cancel out and we find:
x = 7
Then we use x =7 in calcucating equation A) and B)
A) 2y + z = 3
B) -y + 3z = -19
THEN solve for y and z by eliminating variables.

Answer:
38.70 miles
Step-by-step explanation:
Each week, Reuben jogs ...
(2.25 mi)(1 +1 +1 +1 +1 +1.8 +1.8) = (2.25 mi)(8.6)
Then in 2 weeks, he jogs ...
2(2.25)(8.6) mi = 38.70 mi
Reuben jogs 38.70 miles in 2 full weeks.
