multiplying by 20 gives 10(x-4)-4=7x+1 ... 10x-44=7x+1

( x - 4 )/2 - 1/5 = (7x + 1)/20
:
Assume you mean:
- =
:
If we multiply the equation by 20 we eliminate the denominators
20* - 20* = 20*
:
Cancel out the denominators, leaving us with:
10(x-4) - 4(1) = 7x + 1
:
10x - 40 - 4 = 7x + 1
:
10x - 7x - 44 = 1; subtracted 7x from both sides
:
3x = 1 + 44; added 44 to both sides
:
3x = 45
:
x = 45/3
:
x = 15
:
:
It's a good idea to check solution by substituting 15 for x in the original equation
- =
:
- =
:
- =
:
- =
:
Put all the fraction over 20
- =
