Answer:

Step-by-step explanation:
Let's find a particular solution. We need a function of the form
such that
and


then, 3a= 8, 2b+6a =0 and c+2b = 0. With the first equation we obtain
a = 8/3 and replacing in the second equation 2b+6(8/3) = 2b + 16 = 0. Then, b = -8. Finally, c = -2(-8) = 16.
So, our particular solution is
.
Now, let's find the solution
of the homogeneus equation
with the method of constants coefficients. Let 


then 



and
.
So,
and the solution is
.
1 because 5/6 is almost a whole. It can't be 1/2 because it would have been 3/6. And it's not 2 because it should have been an improper faction
Answer:
y + x = 7
Step-by-step explanation:
Standard form should be
y - 9 = -(x+2)
y = -x -2 +9
y + x = 7
4x= 124
divide both sides by 4 to get x by itself
4x/4= 124/4
Cross out 4 and 4, divide by 4 and then becomes 1*1*x= x
124/4
12/4= 3
4/4= 1
Answer: x= 31
