For what value of w does ?

Question

Accepted Answer

Choice D is correct. To solve the equation, use the distributive property to multiply on the right-hand side of the equation which gives w - 10 = 2 w + 10. Subtract w from both sides of the equation, which gives -10 = w + 10. Finally, subtract 10 from both sides of the equation, which gives -20 = w. Choices A and B are incorrect and may result from making sign errors. Choice C is incorrect and may result from incompletely distributing the 2 in the expression 2( w + 5).
