x+y = 6
x-y = 10
add these two equations together
x+y = 6
x-y = 10
------------------
2x = 16
divide by 2
x =8
x+y = 6
8 + y = 6
subtract 8 from each side
y = -2
the numbers are 8 and -2
Answer:
(1,-5)
Step-by-step explanation:
The given system of inequalities are;

and

The point that is a solution will satisfy the two inequalities.
Checking for (1,-5)
and 
: True
: True
This point lies in the solution region.
Checking for (1,5)
and 
: False
: False
This point does not lie in the solution region.
Checking for (5,1)
and 
: False
: True
This point does not lie in the solution region.
Checking for (-1,5)
and 
: True
: False
This point does not lie in the solution region.
(7+x)+x=15
I did trial and error to get x=4.
The answers 8 nice to know
Answer:
Step-by-step explanation:
y = 2x + 4a/6b y=(12xb+4b )/6b
6yb=12x+4a
a=(-12xb+6yb)/4=
a=3yb/2 -3xb
x=y/2-a/3b
b=2a/(3y-6x)
the solution is for every variable
