Answer:

x = 5

Step-by-step explanation:

1/5(3x - 15) = -4(3/5x - 3)

Distribute the 1/5 in.

3x/5 - 3 = -4(3/5x - 3)

Distribute the -4 in.

3x/5 - 3 = -12x/5 + 12

Multiply both sides by 5.

3x - 15 = -12x + 60

Add 15 to both sides.

3x = -12x + 75

Add 12x to both sides.

15x = 75

Divide both sides by 15 to get

x = 5

Proof:

1/5(3x - 15) = -4(3/5x - 3)

1/5(3(5)-15) = -4(3/5(5) - 3)

1/5(15 - 15) = -4(3 - 3)

1/5(0) = -4(0)

0 = 0

Suppose that A is nonsingular. Prove that its inverse A-1 is unique. [Hint: Show that if there exists two matrices, B and C, suc

Bogdan [553]

Answer with Step-by-step explanation:

Let A is non-singular

$\mid A\mid\neq 0$

We have to prove that $A^{-1}$ is unique.

Suppose B and C are inverse of A such that

$BA=I$ and AC=I

By using property $AA^{-1}=A^{-1}A=I$

$C=C$

$(BA)C=B(AC)$

$I\cdot C=B\cdot I$

$C=B$

Hence, the inverse of A is unique.
