Consider the given equations
4x-3y=15----(1)
3x-2y=10----(2)
Use the addition method to eliminate y
Multiply the first equation by 2 and multiply the second equation by (−3)
Then,
-x=0
Put the value of x in the equation (1), then
So,
4(0)-3y=15
y=15/3
y=-5
(x, y)=(0, -5)
Hence, the require number that is multiplied to the second equation is −3

find the solution to the problem y = ( 1 1 0 1 ) y , y ( 0 ) = ( 4 0 )
I know i have to find the eigenvalues and eigenvectors of the matrix A = ( 1 1 0 1 )
there's only one eigenvalue which is 1 and only "one" eigenvector and we can choose ( 1 0 )
but now I dont know what to do.

Help with a system of inequalities with absolute values
{ | x 3 | < 2 x | 2 x + 5 | > 3
The steps I'm taking are:
Finding the absolute values sings, so for x 3 0 we have x 3 therefore
| x 3 | = { x 3 for  x 3 x + 3 for  x < 3
and
2 x + 5 0 we have x 2 5 therefore
| 2 x + 5 | = { 2 x + 5 for  x 2 5 2 x 5 for  x < 2 5
So I build a few systems with the complete inequalities, for the first one we have:
{ x 3 x 3 < 2 x = x > 3
So the solution here would be x > 3, then:
{ x < 3 x + 3 < 2 x = x > 1
The solution would be 1 < x < 3, then
{ x 2 5 2 x + 5 > 3 = x > 1
So the solution of the system is x > 1, then
{ x < 2 5 2 x 5 > 3 = x < 4
And the solution is x < 4
