3 times some number decreased by 5 is no less than 16.

`\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}`

3n-5≥16

`\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}`

First, notice it says "no less than 16"

So the expression can't be less than 16, so it's greater than or equal to 16.

Now, let the number be n.

Multiply 3 times n:

3n

"Decreased by 5" means you subtract 5:-

3n-5

Inequality:- 3n-5≥15

Solve:

3n-5≥15

3n≥15+5

3n≥20

n≥20/3

Good luck.
