What is the difference between a subset and a proper subset?

Originally Answered: What is the difference between a subset and proper subset? The set is a subset of the set if every element of is also an element of . It's a proper subset if it's a subset but not equal to . That implies there's at least one element of that is not an element of .

Step-by-step explanation:

Subset (maths): A set of which all elements are contained in another set.

Proper subset (maths): A proper subset is where all the elements of one subset are entirely contained within another subset, and the other subset also contains more items

Example A={1, 2, 3, 4} is a proper subset of B={1, 2, 3, 4, 5}

A proper subset can be represented as A⊆B

step-by-step explanation:

negitive slope

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
