Final answer:
The correct equivalent equation to find w when 4 is solved is D) 2w = 4. This equation simplifies to w = 2.
Step-by-step explanation:
In order to find an equivalent equation to solve for w when 4 is solved, we need to consider the provided equation, which is 2. The correct equivalent equation is option D) 2w = 4. This equation simplifies to w = 2, which means that when 4 is solved, the value of w is 2. Option A) w - 2 = 0, option B) 4w = 8, and option C) w + 2 = 0 do not represent equivalent equations to find w when 4 is solved.
