12(r-2)=36
1) First, distribute the 12
12r-24=36
2) then, add 24 to both sides
12r=60
3) next, divde both sides by 12
r=5
adn you get r=5

Well, you start off by multiplying 12 into the parentheses. That will give you !2r-24=36. Then you add 24 to both sides. This will leave you with 12r=60. Then you divide 12 from 60 and that would make r=5.

12(r-2)=36, original problem
distribute the 12
12r-24=36
add 24 to both sides
12r=60
divide by 12
r=5
r=5 is the answer

12(r-2)=36 (12/36=3)
r-2 = 3 +2 = 5
r= 5

12(r-2)=36 12 times r equals 12 r 12 times 2 equals 24
12r-24=36
24+36=60
12r=60
60 divided by 12 equals 5
12r divided by 12 equals r
r=5

12(r-2)=36
(r-2)=36/12
(r-2)=3
r=3+2
=5
So r=5.

12(r - 2) = 36
12r - 24 = 36
12r - 24 + 24 = 36 + 24
12r = 60
12r/12 = 60/12
r = 60/12
r = 5
The answer is r = 5
insert the r value into the equation
- - - - - -- - - - - - - -- - - - - - - - --
12( r - 2) = 36
12(5 - 2) = 36
12(3) = 36
36 = 36
- - - - - - - - -s-

divide 36 by 12
(r-2)=3
r-2=3
add 2
r=5

First you would divide both sides by 12. Getting 1(r-2)=3 Then you would add two to both sides....getting 5.
