"x3" is not an inequality. An inequality will have one of the following signs: less-than, less-than-or-equal, greater-than, greater-than-or-equal. for example: 3x - 5 < 15
x3 6x2-x-30
One because if x3 = 1 then x must equal 1
There can be no solution set because there is no equation or inequality, only an expression.
None because without an equality sign the given expression is not an equation and so therefore no solutions are possible.
-37
Since that isn't an equation, there is really nothing to solve.
84x3y
The answer will depend on what the operation is and also whether the solutions are ordered sets (eg coordinates in 4-d space) or simply numbers.
x3 - 5 ≥ 65
125x3 + 1 ???????? 53 * x3 + 1 ================?????
It could be x3 + 2x + 0It could be x3 + 2x + 0It could be x3 + 2x + 0It could be x3 + 2x + 0
