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.
