What is the first step to solve the inequality x-5< x over 6


A.
Divide both sides of the inequality by 6 to simplify: x over 6 - 5 over 6 < 6


B.
Divide both sides of the inequality by x to simplify: 1- 5 over x < 6


C.
Multiply both sides of the inequality by x to simplify: x-5 < 6
D.
Multiply both sides of the inequality by 6 to simplify: 6x-30 < x

1 answer

To solve the inequality \( x - 5 < \frac{x}{6} \), we need to choose an appropriate step to get it into a more manageable form.

Let's examine the options:

A. This suggests dividing both sides of the inequality by 6. However, that approach may complicate the expression rather than simplify it.

B. Dividing both sides by \( x \) is not advisable, especially if \( x \) can equal zero, as it would not maintain the validity of the inequality.

C. Multiplying both sides of the inequality by \( x \) will depend on whether \( x \) is positive or negative, which can lead to issues. It's not a recommended first step because it may change the direction of the inequality.

D. This suggests multiplying both sides of the inequality by 6. This is a valid approach and will help eliminate the fraction.

Thus, the first step to solve the inequality \( x - 5 < \frac{x}{6} \) is:

D. Multiply both sides of the inequality by 6 to simplify: \( 6(x - 5) < x \)

Now implementing option D allows for an easier manipulation of the terms. You would get:

\[ 6x - 30 < x \]

Which you can then proceed to solve.
