Answer:
Step-by-step explanation:
It is a linear homogeneous differential equation with constant coefficients:
y" + 4y = 0
Its characteristic equation:
r^2+4=0
r1=2i
r2=-2i
We use these roots in order to find the general solution:
They both equal the same thing
(6 x 3) x 2 = 36
6 x(3 x 2) = 36

Step-by-step explanation:
2x-y=11 ,6x-3y=15
4x+4y=26
-4y. -4y
4x=22
4. 4. divided
x=5.5 if its wrong and fix something that's wrong
