What is the solution to the equation above?
A
0
B
2
C
3
D
5
Correct answer: B
Explanation
Choice B is correct. Since is equivalent to 1, the right-hand side of the given equation can be rewritten as , or . Since the left- and right-hand sides of the equation have the same denominator, it follows that . Applying the distributive property of multiplication to the expression yields , or . Therefore, . Subtracting x and 2 from both sides of this equation yields .
Choices A, C, and D are incorrect. If , then . This can be rewritten as , which is a false statement. Therefore, 0 isn’t a solution to the given equation. Substituting 3 and 5 into the given equation yields similarly false statements.
