Answer:
Explanation:
Given equation:
To solve for the given equation for x, we need to rearrange the equation to isolate x.
Begin by adding x to both sides of the equation:
Now, subtract 4 from both sides:
Factor out x from the left side of the equation:
Finally, divide both sides of the equation by (2y + 1):
In a rational equation, if the denominator is equal to zero, the equation is undefined. In this case, the denominator is equal to zero when y = -¹/₂, therefore:
