Given:

3/4x + 1/4  = 2x 

Solve for x.

Solution:

In order to find the value of x, we simply need to transpose ¾x on the other side of the equation hence we must take note that in transposing numbers, the sign changes.

3/4x + 1/4  = 2x 

2x - ¾x = ¼

2x can be written as 8/x in order to compute easily.

8/4x - ¾x = ¼

5/4x = ¼

Now in order to determine the value of x, we multiply both sides by 4/5 which is the reciprocal of 5/4. 

(4/5)(5/4x) = ¼ (5/4)

x = 5/20

x = 1/5

Final answer:

x = 1/5
