154a - 5 is not an equation, as there is no relation between two unknowns, or an unknown or a known.
But to answer your question, 5 is always equal to 5, except when 5 is a constant function, in which case it is a function which is always equal to 5, but is not 5 itself - because 5 itself is a scalar while the function 5 is a function.
No, this is an "expression". An equation would include an equal sign, for example:2x + 5 = 11No, this is an "expression". An equation would include an equal sign, for example:2x + 5 = 11No, this is an "expression". An equation would include an equal sign, for example:2x + 5 = 11No, this is an "expression". An equation would include an equal sign, for example:2x + 5 = 11
h5-9-19 is not an equation. An equation must have an equal sign.
no. eg. x < 5
You need a full equation. For example, i could be 1n=5, which you would divide 5 by 1 and n=5. But you need an equation.
1/2x=-5

Yes. Any number, or expression, is equal to itself. An equation such as:x + 5 = x + 5 is true for ANY value of "x".
Y=3x+5
equation
An equation where x = 605.
If y = 2t + 5, then 5 = y - 2t
Any statement that two numbers are equal, such as: 5 = 5 or: 5 = 6 While the second statement is not true, it is still an equation.
