Let's translate the expression step by step:
"Five less than..." [tex] \to [/tex] we will have to subtract five from something
"two times a number" [tex] \to 2t [/tex].
So, we have
"Five less than two times a number" [tex] \to 2t-5 [/tex].
This "is sixty-nine", where "is" means "is equal to". So, the equation is
[tex] 2t-5=69 [/tex]
which is option B
