Question

Find r. Show all your work. -24+3r=9

Answer 1

r = 11

Explanation:

Solve for r:

3 r - 24 = 9

Add 24 to both sides:

3 r + (24 - 24) = 24 + 9

24 - 24 = 0:

3 r = 9 + 24

9 + 24 = 33:

3 r = 33

Divide both sides of 3 r = 33 by 3:

(3 r)/3 = 33/3

3/3 = 1:

r = 33/3

The gcd of 33 and 3 is 3, so 33/3 = (3×11)/(3×1) = 3/3×11 = 11:

Answer: r = 11

Answer 2

r=11

Explanation:

First thing you should do is add 24 to both sides. This is

-24+3r+24=9+24

Then you would get:

3r=33

Next you would do

33/3

To find:

r=11
