Answer:
the solution is (-4, 2)
Step-by-step explanation:
6x + 8y = -8
x + 4y = 4
... can be solved using elimination by addition and subtraction, among other methods. Multiply the second equation by -2 to obtain
6x + 8y = -8
-2x - 8y = -8
Combining these results in
4x = -16. Thus, x = -4.
Substituting -4 for x in x + 4y = 4 results in
-4 + 4y = 4, or 4y = 8, or y = 2
Then the solution is (-4, 2)

Answer:
Step-by-step explanation:
Given that:
is a supplement of 
.
m = 78°
To find:
m = ?
Solution:
First of all, let us learn about the concept of an angle being a supplement of the other angle.
is known as supplement of 
, if sum of the two angles is equal to 180°.
.
For example, angle made on one side by a line intersecting the other line are supplement of each other.
Here, we are given that is a supplement of .
In other words:
Putting value of :
So, the answer is:
