en.wikipedia.org/wiki/Algebraic_equation

In mathematics, an **algebraic equation** or polynomial equation is an equation of
the form. P = Q {\displaystyle P=Q} P=Q. where P and Q are polynomials with
coefficients in some field, often the field of the rational numbers. For most authors,
an **algebraic equation** is univariate, which means that it involves only one
variable.

where a and b are real numbers and x is a variable. This form is sometimes
called the standard form of a linear **equation**. Note that most linear **equations** will
not start off in this form. Also, the variable may or may not be an x so don't get too
locked into always seeing an x there. To solve linear **equations** we will make
heavy ...

Example: x − 2 = 4. When we put 6 in place of x we get: 6 − 2 = 4. which is true. So x = 6 is a solution. How about other values for x ? For x=5 we get "5−2=4" which is not true, so x=5 is not a solution. For x=9 we get "9−2=4" which is not true, so x=9 is not a solution. etc. In this case x = 6 is the only solution.
