Work Step by Step
An equation is a mathematical statement in which it is claimed that two mathematical expressions are equal.
An equation is written in the form
(expression on the left side) = (expression on the right side of the equality sign),
that is, the two expressions are on either side of one equality sign (=).
Examples:
$2x=5+7x,$
$x-2y+9=3,$
$\displaystyle \frac{n+3}{7}-1=0$
