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
