Step 1
First step is to multiply by 4,
by dong this you can cancel out the fraction ( 1 4 )
then, you'll get 5 x + 1 = 12 x now subtract an divide, you should get 1 7 .
to check plug in 1 7 where the x is in the original equation you will get 3 7 = 3 7

Step 1
You would multiply each side by 4.
You want to eliminate anything which might complicate solving for x,
and having a 1 4 around is a hassle at this point.
Multiplying by 4 removes the 1 4 from the left side, and makes the right side a 12x.
From there, simply isolate X and voila.
