Answer:

x is -2

Step-by-step explanation:

1. write your problem out on a scratch piece of paper

2. distribute your -5 to 6x and that gives you -30x

3. distribute your -5 to your 6 which gives you -30

4. now write down the problem again so that you have 30= -30x - 30

5. add 30 to your 30 on the left of the equals and to the -30 on the right of it

6. now you should have 60 = -30x

7. divide everything by -30

8. finally you should get -2 = x

9. very last flip it so that the x is on the left of the equals sign

So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.

So the equation is $2.25x \leq 5$
Then we solve by isolating the x. We divide 2.25 both sides then we get $x \leq 2$
