Question

Tell whether x=6 is a solution of x−1 ≤ 7.

Answer 1

Answer:

B. NO

Step-by-step explanation:

I'll show you how to figure this thing out.

You have to isolate by the term of x from one side of the equation.

$\sf{x-1\leq7 }$

First, all you have to do is add by 1 from both sides.

$\sf{x-1+1\leq7+1}$

Then, you solve.

$\sf{7+1=8}$

$\boxed{\sf{x\leq8}}$

Therefore, the solution is x≤8, which is our answer to this question.

Almost forgot, the correct answer is B. NO.

I hope this helps! Let me know if my answer is wrong or not.

Answer 2

Answer:

x = 6 is a solution of x - 1 $\leq$ 7.

Step-by-step explanation:

First, plug in x = 6 into the inequality.

x - 1 $\leq$ 7 for x = 6

6 - 1 $\leq$ 7

Now, solve.

6 - 1 = 5

5 $\leq$ 7

The statement above is true, so x = 6 is a solution to x - 1 $\leq$ 7.
