You simply do the direct substitution,
you remove m and put the number of months given,
b=540-(30*9)= 270$
This example gives you an equation where calculates how much your balance is, an equation of b (balance) as a function of m (number of months), so simply substitute with the number of months given to you into the equation and you get the answer.
Hope this helps.

8+—3(6+—6a) help please

LenKa [72]

We know that:

$(+)+(-)=(-)$

and:

$(-)*(+)=(-)$

$8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a$ $=(-10)+18a$

if you have solve for $a$ then:

$(-10)+18a=0$
$18a=10$
$a= \frac{10}{18}$
$a=\frac{5}{9}$
