The main difference is that if you multiply or divide by a negative number, you need to simultaneously invert the inequality - for example, a less-than sign becomes a greater-than sign. Example:
-2x < 15
Multiplying by -1/2 (equivalent to dividing by -2):
x > 7.5
That is not an inequality. An inequality must have <, >, <=, >=.
The solution to an inequality generally is a region with one more dimension. If the inequality/equation is of the form x < a or x = a then the solution to the inequality is the 1 dimensional line segment while the solution to the equality is a point which has no dimensions. If the inequality/equation is in 2 dimensions, the solution to the inequality is an area whereas the solution to the equality is a 1-d line or curve. And so on, in higher dimensional spaces.
This is an expression, not an equality (or inequality). It, therefore, cannot have a solution.
its different
x^4 is not an inequality. (An inequality has a "bigger than or equal to/less than or equal to/less than/bigger than" sign involved. I.e not an "equals" sign, since this would be an "equality"). But x^4 is not an equality, nor an inequality.

Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.Substitute the values of the variables into the inequality.

Nothing will solve an expression. You need an equation (an equality or an inequality) beofre a solution of any kind is possible. Tha means you need something on both sides of the equality (or inequality) sign.
There is no solution set. x + 57 is an expression, not an equality, nor even an inequality. An expression CANNOT be solved!
An equality defines a specific point (or points). An inequality can define an interval.
Quality, equality,
Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33
