Answer:
see explanation
Step-by-step explanation:
The 2 equations are
x + 2y = 8 → (1)
2x + 4y = 20 → (2)
G=3M
G+M=56
-------------------------------------------
3M+M=56
4M=56
M=56/4=14
---------------------------------------------
G+14=56
G=42
---------------------------------------------
So Gabriel is 42 and Mikhail is 14.
Answer:

Step-by-step explanation:
Length of LJ is
which is 
Now, in triangle LMJ the both angles are 45 degrees,
so 

x=4
Use p.e.m.d.a.s.
