Кто поможет решить матрчное уравнение?

Х(-12+10)=-6+10

-12Х+10Х=4

-2Х=4

Х=-2

X = (x1  x2)

      (x3 x4)

3x1 + 5x2 = -1

-2x1 - 4x2 = 2

3x3 + 5x4 =  -5

-2x3 - 4x4 = 6

=gt;

x1 + x2 = 1 =gt; x1 = 1  - x2

x3 + x4 = 1 =gt; x3 = 1 - x4

=gt;

3 - 3x2 + 5x2 = -1 =gt; 2x2 = -4 =gt; x2 = -2 =gt; x1 = 1 + 2 = 3

3 - 3x4  + 5x4 = -5 =gt; 2x4 = -8 =gt; x4 = -4 =gt; x3 = 1 + 4 = 5
