Question

can somebody please help me with 64 = 8 ( r + 2) ?

Answer 1

okay so distribute
8(r+2)

Answer 2

you would get
8r + 16

Answer 3

remember the distributive property:

a(b + c) = (a * b) + (a * c)

Answer 4

so now we have
64 = 8r + 16

Answer 5

64= 8r + 16
-16 =8r -16

Answer 6

48= 8r

Answer 7

now subtract 16 from both sides
64 = 8r + 16
-16 -16
--------------
48 = 8r now divide 8 from both sides
/8 /8
----------
r = 6

Answer 8

r=6
