B) Equivalent

Question

Quizplus · Accepted Answer

The equations are not equivalent because when you solve each equation for x, you get different values. For the first equation, adding 3x to both sides gives 4x = 1, so x = 1/4. For the second equation, dividing both sides by 2 gives x = 1/2. Since 1/4 does not equal 1/2, the equations are not equivalent.
