Step-by-step explanation:
The equation is written as: [tex]3x-5\geq 16[/tex]
You can make it a 2 step equation.
[tex]3x-5\geq 16\\[/tex]
16+5=21
[tex]3x\geq 21[/tex]

3 times some number decreased by 5 is no less than 16.
[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]
3n-5≥16

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
