Solve. x/3 � 4 = 1
:
- 4 = 1
:
The first thing you want to do, is get rid of that annoying fraction.
Multiply equation by 3 to do that (you mult each term by 3):
:
3* - 3(4) = 3(1)
:
Cancel out the denominator and you have
x - 12 = 3
:
x = 3 + 12; added 12 to both sides
:
x = 15
;
:
Confirm our solution by substituting 15 for x in the original equation:
- 4 = 1
5 - 4 = 1
:
