No they do not, equations have equal signs.

It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
An expession has NO equal sign, a equation are to amounts that are equal
expressions don't have an equal sign and equations do

Equations are made from expressions.
Equations are mathematical statements that show the equality of two expressions, typically separated by an equal sign. They are used to solve for unknown variables by manipulating the expressions to find a solution that satisfies the equation. Equations play a fundamental role in mathematics and are used in various fields to describe relationships between quantities.
They are the same except equations use the equal sign =
They can but don't have to.
In the same way that you would solve equations because equivalent expressions are in effect equations
