You can represent values using variables. This can only be done with whole numbers.
A systematic approach is completing tasks using a step by step method. An example of systematic approach is solving problems using steps that can be repeated and learned from.

The four steps to solving equations are. First it is necessary to simplify the equation by using the distributive property where applicable and combining like terms. Next, it is necessary to collect all the variables together on one side of the equation by adding or subtracting from each side. Using inverse operations for addition and subtraction can remove constants next, to get the variables and constants on opposite sides. Lastly, inverse operations can be used to eliminate coefficients in front of variables to get the variables by themselves. It is important to remember that when multiplying or dividing an inequality by a negative number, the direction of the inequality sign will need to be flipped.
It is algebra.

Standard form for equations of two variables is preferred when solving the system using elimination.
Math involves using your brain power and solving problems. Take it as solving riddles and decoding a puzzle or code...
Problem solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems.
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
