Step-by-step explanation:
The expression that represents the amount that was not paid off is 
<u>Solution:</u>
Given, In 1995, the federal government paid off one-third of its debt. If the original amount of the debt was $ 4.920,000,000,000
We have to find which expression represents the amount that was not paid off
Now, we know that, amount that is not paid off = total debt – paid amount


Hence the expression and value of debt amount that is not paid off is found
To solve an equation for x we will try to isolate x. Hence, first step is to use the distributive property. Therefore,
4x + 29 = 5 - 8(x+6)
4x + 29 = 5 - 8x - 48
4x + 29 = - 43 -8x Combine the like terms.
4x + 29 + 8x = -43 Add 8x to each sides of the equation.
12x + 29 = -43
12x = -43 - 29 Subtract 29 from each sides.
12x = -72

So, x =- 6
