Answer:
Step-by-step explanation:
I don't know if this is what you are looking for but, I would use substitution to solve what x and y are
6x+2y = 1
is the same as -6x-2y= -1 because if you multiply everything by -1 it will equal
6x+2y = 1
so now you have
6x+2y = 1
6x+2y = 1
I would set the equation equal to one variable and substitute.
6x+2y = 1 = 2y = 1 - 6x = y = (1/2) - (6x/2) = y = (1/2) - 3x
now plug in (1/2) - 3x in to one of the y's because they are the same equation
6x + (1/2) - 3x = 1
subtract 1/2
6x - 3x = 1/2
subtract the x's
3x = 1/2
now divide both sides by 3
x = (1/2)/ 3
x = 1/6
now that you know what x equals, plug that into the equation and find y
6(1/6) + 2y = 1
1 + 2y = 1
subtract 1
2y = 0
now divide to find y
y = 0/2
y = 0
so
x = 1/6 and y = 0

A-b=6
</span>
<span>A-2b=2
-2(A-b=6)
-2A+2b= -12
A-2b=2
-2A+2b = -12
-------------------
-A = -10
-A/-1 = -10/-1
A = 10
a-b=6
10 - b = 6
10-10-b = 6 -10
-b = -4
-b/-1 = 14/-1
b= 4
Check
a - 2b =2
10 - 2(4) =2
10 - 8 = 2
2=2

Answer: (-2,-4)
Step-by-step explanation:
To find the midpoint between two points we need to find the mean average between the x and the y .
Since we know the midpoint will have to represent the missing coordinates by the variables.
Solve for x to find the x coordinate by first multiplying both sides by -4.
-6 + x = -8 Add -6 to both sides
+6 +6
x = -2
The x coordinate of the B is -2 now we need to find the y coordinate.
Multiply both sides by 2
4 + y = 0 Subtract 4 from both sides
-4 -4
y = -4
The y coordinate is -4 so the coordinates will be (-2,-4)

Answer:
k=8
Step-by-step explanation:
divide both sides by 11 to get nine
then subtract 1 from both sides to get
8
