$a \geq 17$ $a>= 17$

Explanation:

$distribute the bracket$ $"distribute the bracket"$

$\Rightarrow - 20 + 5 a \geq 65$ $rArr-20+5a>=65$

$Isolate 5a by adding 20 to both sides$ $"Isolate 5a by adding 20 to both sides"$

$cancel(-20)cancel(+20)+5a>=65+20$

$rArr5a>=85$

$"divide both sides by 5"$

$(cancel(5) a)/cancel(5)>=85/5$

$rArra>=17" is the solution"$
