### This Is a Certified Answer

Certified answers contain reliable, trustworthy information vouched for by a hand-picked team of experts. Brainly has millions of high quality answers, all of them carefully moderated by our most trusted community members, but certified answers are the finest of the finest.
1.)
(3)(5)=15,then (3)(5)·4=15·4;this is a mathematical equation/equality since it shows an equal sign and does not consists an inequality symbol.

2.)
4>2,then 4+15>2+15;this is a mathematical inequality since the mathematical expression consists of inequality symbol.

3.)
5·6=30 and30=3·10,then 5·6=3·10;this is a mathematical equality since it shows an equality sign and not an inequality symbol.

4.)
x+y=5 and x=3,then 3+y=5;this is an mathematical equation/equality since it consists of an equality sign.

5.)
12=12;this is a simple mathematical equality because it has an equal symbol.

6.)
3·4=12 and 12=2·6,then 3·4=2·6,this is a mathematical equation\equality since it has an equality symbol.

Points to remember;
It is an inequality statement if it consists of this inequality symbols;≠,≤,≥,<,>
While,it is an equation or equality if it consist of these one and only symbol =.

Hope it Helps:)
