To figure out which is not equivalent to the others,, we must solve each option provided. x < -2 is already solved,, so there is no need to do any work that option. The first step for solving x - 2 < 4 is to move the constant to the right side and then change its sign. x < 4 + 2 Now add the numbers together to get your final answer. x < 6 This means that we have one option that equals x < -2 and one option that equals x < 6. Let's now solve 2x < -4 to see what that one equals. In order to solve this,, we need to divide both sides of the inequality by 2. x < -2 Now we can see that it looks like all of the expressions are equivalent except for x - 2 < 4. Before we can confirm this though,, let's solve for x - 2 < -4. The first step for solving this is to move the constant to the right side and change its sign. x < -4 + 2 Now calculate the sum of these two numbers to get your final answer. x < -2 This tells us that all of the options are equivalent except for x - 2 < 4,, or option B. Let me know if you have any further questions. :)
You could give all of the fractions a common denominator. You could also solve each of them (1/2=0.5) to see their value and order them through the value.
