Question

-3 (5-b)= Use the distributive property to rewrite this expression

Answer 1

= -3 (5-b) 
= -3 (5 + (-b))
= (-3 x -b) + (-3 x 5)
= 3b + (-15)
= 3b -15

Answer 2

-3 ( 5 - b ) =
-15 + 3b = 
That is how you rewrite it, because it means the same thing.
-3 ( 5 - b ) = 
-15 + 3b = 
+15            +15
3b = 15
/3      /3
b = 5 
incase you wanted to know how to solve to.
 I hope this helped, HAVE A NICE DAY.
