First add 1 to both sides, thus making it 4r=36 then divide both sides by 4, making r=9.

4r-1=35
   +1  +1
4r=36
4     4
r=9
Salutations!

4r-1=35 (solve)

4r - 1 = 35

Isolate the numbers

[tex]4r = 35 + 1[/tex]

[tex]4r = 36 [/tex]

[tex]r = 36/4 [/tex]

[tex]r = 9[/tex]

Hope I helped (:

Have a great day!
