Question 837803



twenty more than four times a number is equal to the difference between -58 and twice the number. find the number


-----------------------------------
1st.)

twenty more than = +20


-----------------------------------
2nd.)**Note: Let n= a number

four times a number= 4*n   (or could be written as 4n)


-----------------------------------
3rd.)

is equal to: =


-----------------------------------
4th.)

the difference between -58 and twice the number= -58-2n


-----------------------------------
5th.) Using what we got in step 1 and 2 we can "build" left side of equation.

4n+20


-----------------------------------
6th.) Using what we got in step 4 we can "build" right side of equation.

-58-2n


-----------------------------------
7th.) Put step 5 and 6 together and use equal sign from step 3.


4n+20=-58-2n


----------------------------------
8th.) Solve.

4n+20=-58-2n
4n+2n+20=-58-2n+2n
6n+20=-58
6n+20-20=-58-20
6n=-78
6n/6=-78/6
n=-13



-----------------------------------
9th.) Answer.


n= -13
