x2 = 16
take the root square for both sides the result will be :
X = +4 or -4
16 = 16 is an identity, not an equation. An identity does not have solutions.
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
There is only one solution to that equation. It's . . . . . x = -16

It is an inequality that defines a range of values of p for which it is correct.
16 = 16 is an identity, not an equation. An identity does not have solutions.
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
There is only one solution to that equation. It's . . . . . x = -16
8x = 16 is NOT an 'Inequality#'. However, 8x > 16 is an inequality as is 8x > 16 . NB Treat inequalities as an 'equals'. except for negative numbers or fractions. Hence 8x > 16 Divide both sides by '8' x > 2 Similarly 8x < 16 x < 2
If x2 = 16 then this is not written as an inequality.An inequality tells us that one thing is not equal to another.The above is an equation, because it is telling us that one thing is equal to another.If x2 = 16 then x = 4 & -4.

That's not an inequality; an inequality needs a "greater than" or a "less than" sign. Those must have gotten lost when you typed the title. Anyway, basically you are supposed to replace the numbers one by one in the inequality, do the calculations, and see whether the resulting statement is true or not.

This is not an inequality. There is no <,>, or = sign.
