Question

Fifteen less than twice a number is less than or equal to -23

Answer 1

Hello!

First of all, let the number be y.

"twice a number" means you should multiply that number by 2:

2y

Now, "fifteen less" means you should subtract 15:

2y-15

Now, this whole expression is less than or equal to -23:

2y-15≤-23

`\rule{150}{1}~\rule{150}{2}`

Solve the inequality:

• Add 15 to both sides

2y≤23+15

2y≤38

Divide both sides by 2

y≤19

Hope everything is clear.

Let me know if you have any questions!
