Answer:
Maybe its because you give useless answers to get points.
Idiot.
Answer:
No solution.
Step-by-step explanation:
2x + y = 7
-2x - y = 6
From the first equation:
y = 7 - 2x
Plug this into the second equation:
-2x - (7 - 2x) = 6
-2x + 2x = 6 + 7
0 = 13
this doesn't make sense so theer is:
No solution.
32 40%
80 100
to find the answer, you do 32 times 100, the. divide that by 40 which equals 80
