Multiplicative identity
It follows from the multiplication property of equality. Dividing both sides of an equation by the same number (not by zero, of course) is the same as multiply both sides of the equation by the number's reciprocal. For example, dividing both sides of an equation by 2 is the same as multiplying both sides by 0.5.
Associative? Commutativity?
true
That means that subtracting the same value or expression from both sides of an equation is a valid operation, in the sense that the new equation will have the same solution set. The definitions of "addition property...", "multiplication property..." and "division property..." are similar; with the main caveat that you may not multiply or divide by zero.
The short answer, multiply on both sides of the equation by the inverse of the matrix you need to remove. Just like solving 3x = y for x. Multiply on both sides of the equation by 1/3.
im not a 100 percent sure but i think its.... Multiplication Property of Equality
The addition property of equality states that if you add the same number to both sides of an equation, then the sides remain even. This means that the equation remains to be true.

The Addition Property of Equality states that if you add the same number to both sides of an equation the two sides remain equal. Source- My mathbook.
Yes, it should be non-zero; if you multiply both sides by zero you wipe out the equation.
false
true
Multiply both sides ofthe equation by the 'denominator' of the fraction.

States that two sides of an equation remain equal if multiplied by the same number. usually seen algebraically as: if a = b, then ac = bc this is the property that allows you to "move" a number to the other side of the equation by multiplying or dividing both sides by the same number.
