Solve for r.
5r - -17r - 4r + -9 = 9


Sagot :

15 + 17r - 4r - 9 = 9
6 + 13r = 9
13r = -3
r = -3/13

Answer:

r=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5r−−17r−4r−9=9

5r+17r+−4r+−9=9

(5r+17r+−4r)+(−9)=9(Combine Like Terms)

18r+−9=9

18r−9=9

Step 2: Add 9 to both sides.

18r−9+9=9+9

18r=18

Step 3: Divide both sides by 18.

18r/18 = 18/18

r=1
