solvefor X,DXD^T=2D(X+3I)

solve for

X, D X D^{T} = 2 D (X + 3 I)

X = \frac{6 I}{D ^{T} - 2}; X (X^{T} - 2) \neq = 0

Solution steps

D X D^{T} = 2 D (X + 3 I)

Expand

D X D^{T} : D^{1 + T} X

Expand

2 D (X + 3 I) : 2 D X + 6 D I

D^{1 + T} X = 2 D X + 6 D I

Move

2 D X

to the left side

D^{1 + T} X - 2 D X = 6 D I

Factor

D^{1 + T} X - 2 D X : D X (D^{T} - 2)

D X (D^{T} - 2) = 6 D I

Divide both sides by

D (D^{T} - 2); X (X^{T} - 2) \neq = 0

X = \frac{6 I}{D ^{T} - 2}; X (X^{T} - 2) \neq = 0

2 (5 p - 1) - 2 p = 4 p + 2

\frac{2}{3} t - \frac{1}{5} t = 2

x, y - 3 = \frac{1}{3} (x + 4)

x - \frac{( \frac{1 - 3 x}{4} )}{4} = \frac{( 2 - \frac{x}{4} )}{3} + 10 \frac{3}{4}

y, 6 x y = x^{4} + 3
