Hi!
The table above is showing how to plug in a variable to x. For an example,
5x - 3 =?
when x= 4 would equal 17. How we would get this is substitute x with 4 and use our order of operations.
5(4) - 3 = 20 - 3 =  17
To get 68, we would do this in reverse. We would add 3 to both sides to eliminate the -3 to have a remainder of
5x  =  71
Divide both sides by five to solve for x.
x = \frac{71}{5}
We can also check our math and plug in 17/5 into x
5( \frac{71}{5} ) - 3 =71 - 3 = 68

Write down the inequality for x that is shown on this line.
boyakko [2]

Answer:

x > 3

Step-by-step explanation:

Here, we want to write the inequality represented

We start by looking at the value on which we have the circle

It is on the value 3

we can also see that the circle is unshaded and also that, the graph faces the right direction

As the circle

is unshaded, we have it that we only use the inequality without the equal to

So we have the representation as;

x > 3
