To solve the equation, we need to isolate the variable x.
Given equation: 1/4 + 1/2x = 4
First, let's get rid of the fraction by multiplying every term in the equation by the least common denominator (LCD), which is 4:
4 * (1/4) + 4 * (1/2x) = 4 * 4
This simplifies to:
1 + 2/x = 16
Next, let's subtract 1 from both sides of the equation:
1 - 1 + 2/x = 16 - 1
2/x = 15
Now, let's multiply both sides of the equation by x to get rid of the fraction:
2/x * x = 15 * x
This simplifies to:
2 = 15x
Next, let's divide both sides of the equation by 15 to solve for x:
2/15 = 15x/15
2/15 = x
Therefore, the solution to the equation 1/4 + 1/2x = 4 is x = 2/15.
