Answer 2

Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

        +12    +12 (add 12 to the 13)

    5x=25  

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64  (first use distributive property)

   8x+24=64

        -24   -24    (then subtract 24 to 64 which is 40)

    8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D
