Answer:

m = $3 and b = $6

Step-by-step explanation:

Total cost = $9

Since the cost of the magazines is m, therefore, the cost of the books is ($3+m)

==> $3 + m + m = $9

==> $3 + 2m = $9

Subtract $3 from both sides of the equation

==> $3 - $3 + 2m = $9 - $3

==> 2m = $6

Divide both sides by the coefficient of m which is 2

==> 2m/2 = $6/2

==> m = $3

Since m = $3, therefore the cost of books, b =

$3 + $3

= $6

Therefore, m = $3 and b = $6

Hope this helps!!!
