For this case we must find the solution of the following equation:

Applying distributive property on the right side of the equation we have:

Subtracting 7x from both sides of the equation:

Subtracting 20 from both sides of the equation:

Different signs are subtracted and the major sign is placed.

Dividing between -2 on both sides of the equation:

Thus, the solution of the equation is
Answer:

Answer:
$34,000
Step-by-step explanation:
First they had 30,000
Then wrote off 40,000
So balance is 30,000 - 40,000 = -10,000
Now, they want 8% of 300,000 as uncollectible. So that would be
0.08 * 300,000 = 24,000
Thus, to bring the balance to 24,000 [balance is -10,000], how much would they need to add?? Let it be x:
-10,000 + x = 24,000
x = 24,000 + 10,000 = $34,000
-2 -13.8x = -8 -6x -1
First, I distributed the negative 1 that was outside of the parentheses to the positive 6x and the positive 1.
-2 -13.8x = -9 -6x
Then I added the negative 8 to the negative 1 which equals negative 9.
-2 -13.8x +6x = -9 -6x +6x
After that I used the addition property and added a positive 6x to both sides.
-2 -7.8x = -9
Then simplifying.
+2 -2 -7.8x = -9 +2
After simplifying, I used the addition property again, adding a positive 2 to both sides.
-7.8x = -7
Simplified.
-7.8x (-1) = -7 (-1)
Then I multiplied both sides by with a negative 1 since the variable cannot be a negative.
7.8x = 7
Simplified
(1/7.8) 7.8x = (1/7.8) 7
Then, to isolate the veriable, I multiplied 1/7.8 to both sides.
x = 1.11428571429
The answer !
I hope this helped !
Equation= x divided by -9 = -16
solve= 9 x 16 = 144
answer is 144
