“A subset is a collection of items drawn from the original larger set. A subset can have the same number of items as the original set or the count can be smaller. 

Subsets that have 3 items: {3, 4, 7} which is the original set. Any set is a subset of itself. 

---------------------------------------------------------------------------------------

Subsets that have 2 items
{3, 4}, {3, 7}, {4, 7}

---------------------------------------------------------------------------------------

Subsets that have 1 item
{3}, {4}, {7}

---------------------------------------------------------------------------------------

Subsets that have 0 items: the empty set which we write { } or using the symbol 

---------------------------------------------------------------------------------------

So all together we have 8 subsets
{3, 4, 7}
{3, 4}, {3, 7}, {4, 7}
{3}, {4}, {7}
{ }

Side Note: There are n = 3 items in the original set so there are 2^n = 2^3 = 8 subsets possible. The collection of all subsets is known as a power set.”

Part (a)

<h3>Answer:   x = -8</h3>

------------------

Work Shown:

2(x-1) = 3(x+2)

2x-2 = 3x+6 .... distribute

2x = 3x+6+2 .... adding 2 to both sides

2x = 3x+8

2x-3x = 8 .... subtracting 3x from both sides

-x = 8

x = -8 ..... multiply both sides by -1

===========================================================

Part (b)

<h3>Answer:  x = 5/11</h3>

------------------

Work Shown:

-4(2x-2) = 3(x+1)

-8x+8 = 3x+3 ..... distribute

-8x = 3x+3-8 .... subtract 8 from both sides

-8x = 3x-5

-8x-3x = -5 ... subtract 3x from both sides

-11x = -5

x = -5/(-11) .... divide both sides by -11

x = 5/11

In decimal form, this is approximately equal to 5/11 = 0.4545
