This compound inequality cannot be solved.

You need to reverse the inequality symbol when multiplying both sides of an inequality by a negative number because you are changing the sign of both sides of the equation. Since inequality, such as "less than", means "to the left of" on the number line (where left is minus and right is plus) then a number that is less than another will be greater than the other if the signs were reversed. Example: 3 is less than 4, but -3 is greater than -4.

-7

The question contains an algebraic expression but not an equality nor inequality. There is, therefore, nothing that can be solved.

There's nothing to solve. If it equaled something, you could solve it. For example, if x^2 - 28 = 0, then x = the square root of 28, which simplifies to plus or minus 2 times the square root of 7.

Yes

It is not possible to answer the question. An equation or inequality can be solved. However, the question contains no equation nor inequality but only an expression.

so = -4y < -20 making y < 5

Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33

There is one linear inequality in 2 variables: l and x. That is not enough to obtain a solution.

FALSE

You cannot solve x plus y since that is an expression, not an equation (nor inequality).

h <9

There is no equation (nor inequality) to be solved!

It is not possible to "solve" b+815 because it is an expression - not an equation or inequality.

To solve the above inequality equation it has to have an equality sign so that i group all the the knowns and the unknowns.

The inequality sign got lost when writing the question. Anyway, inequalities are basically solved the same way as equations; you transfer everything that has the variable ("x") to one side, and everything else to the other side of the equation - or inequality. The major care you must take is that in an inequality, if you multiply or divide by a negative number, the inequality sign changes direction - for example, a less-than becomes a greater-than.
