Note on Elementary math


Elementary math terms are the basic form of algebra having little or no proper information of mathematics beyond arithmetic. In arithmetic numbers and their arithmetical operations (such as +, −, ×, ÷) occur, in algebra one also uses symbols (such as x and y, or a and b) to denote numbers. Elementary Algebra can be distinguished from abstract algebra, a more advanced field of study.And now we see about the elementary math terms below in simple problems

Solution:-
Now we allocate the above equation:
1 - 3x +12 = 6x + 2 - 7
Collect like terms:
-3x +13 = 6x - 5
Add 3x to both sides of the equal sign: this will also help us on elementary linear algebra
-3x +13 + 3x = 6x - 5 + 3x
13 = 9x - 5
Add 5 to both sides:
18 = 9x
Divide both sides by 9 in above equation :
2 = x
