$a = 36/5$

Divide each side of the equation to isolate $a$ and keep the equation balanced. In this case we need to divide by $-10$ :

$(-10a)/(-10) = (-72)/(-10)$

$(cancel(-10)a)/(cancel(-10)) = (-72)/(-10)$

$a = 72/10$

$a = (2/2) (36/5)$

$a = 1* 36/5$

$a = 36/5$

How do you solve -10a = - 72-10a = - 72?
