We define a company's Net Worth as its assets minus liabilities. Assets are all things of value that may be converted into cash whereas liabilities are the company's total of debts. Now the XY Association went bankrupt while it had $28.6 billion in assets and $26 billion in liabilities.
What was the XY Association's net worth before it went bankrupt?

$1.6 billion

$2.6 billion

$2.9 billion

$0.6 billion

To find the net worth, subtract the debts from the assets. Your answer should be in the billions.
Net Worth = Assets − Liabilities
= 28.6 − 26
= 2.6
Therefore, the XY Association had a net worth of $2.6 billion.

Solve the equation.
4.3x − 0.7(x+ 2.1) = 8.61

x = 2.1

x = 2.8

x = 4.2

x = 6.7

Original equation.
4.3x − 0.7(x+ 2.1) = 8.61
Apply the distributive property.
4.3x − 0.7x − 1.47 = 8.61
Combine like terms on the left side.
3.6x − 1.47 = 8.61
Add 1.47 to both sides.
3.6x = 10.08
Divide both sides by 3.6.
x = 2.8

In the week that ended June 19, the U.S. commercial crude oil inventory decreased by 3.8 million barrels.
Now if the inventory was 353.9 million barrels in the week that followed, what was the U.S. crude oil inventory before the decline?

270.90

320.9

256.2

357.7

Let x represent crude oil inventory in millions of barrels for the previous week before the decline.”
Set up an Equation. “Crude oil inventory last week experienced a decline and result in the crude oil inventory now” becomes Oil inventory last week - decline in inventory = Oil inventory this week
x − 3.8 = 353.9
Solve the Equation. To isolate an unknown value x, add both sides of the equation by 3.8.
Original equation
x − 3.8 = 353.9.
Add both sides of the equation by 3.8.
x − 3.8 + 3.8 = 353.9+ 3.8
