Answer :

Answer:

r = 12

Step-by-step explanation:

DG + GM = DM , substitute values

r + 3 + 4r - 28 = 35 , that is

5r - 25 = 35 ( add 25 to both sides )

5r = 60 ( divide both sides by 5 )

r = 12

You know both the lines added together give you 35
So r+3+4r-28 = 35
Collect like terms
5r-25=35
Add 25 to each side
5r=60
Divide both sides by 5
r=12
