You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.

Make c the subject in:
Substitute in and
![2[5.00 - 3d] + j + 2d = 7.50](https://tex.z-dn.net/?f=2%5B5.00%20-%203d%5D%20%2B%20j%20%2B%202d%20%3D%207.50)
Make j the subject
![3[5.00 - 3d] + j + 4d = 11.50](https://tex.z-dn.net/?f=3%5B5.00%20-%203d%5D%20%2B%20j%20%2B%204d%20%3D%2011.50)
Make j the subject
So, we have:
and
Equate both values of j
Collect like terms
Substitute in
To solve for c, we substitute in
Solve for c
Answer: The total change is 21.
Since you want to find the change from the lowest to highest, make it into a subtraction problem. First of all, take the smallest number in front of the largest.
20 -1
Next, add a minus sign in between, your equation should look like this:
20 - (-1) = x
Then, you cancel out the negative signs. After that you solve it
20 - (-1) -> 20 + 1.
Lastly, you add them together.
20 + 1 = 21.
In conclusion, the answer is 21.
Answer:
The quotient is: x-7
and remainder is : -300
Step-by-step explanation:
We need to divide 
by 
First arrange the term in terms of ascending order of x.
Arranging we get:
\
The division steps are shown in figure attached.
The quotient is: x-7
and remainder is : -300
2v + 18 = 16 - 4(v + 7)
Simplify by removing the parenthesis.
2v + 18 = 16 - 4v - 28
Now, simply add 4v to both sides.
2v + 4v + 18 = 16 - 28
Simplify.
6v + 18 = -12
Now, subtract 18 from both sides.
6v = -12 - 18
Simplify.
6v = -30
Finally, divide both sides by 6.
6v ÷ 6 = 30 ÷ 6
Simplify.
v = 5
