Answer:
6. r=2
8.x=3
Step-by-step explanation:
6. 4r-3=5
4r-3=5 add 3 to both sides
4r=8 divide 4 by both sides
r=2
8. 5x-6=9
5x-6=9 add 6 to both sides
5x=15 divide 5 by both sides
x=3
 
                                
             
                    
              
              
                
                
Question 6) 4r - 3 = 5
First we need to add 3 to each side.
4r - 3 + 3 = 5 + 3
4r = 8
Then we will divide each side into 4 groups.
4r/4 = 8/4
r = 2
Question 8) 5x - 6 = 9
First we need to add 6 to each side.
5x - 6 + 6 = 9 + 6
5x = 15
Then we will divide each side into 5 groups. 
5x/5 = 15/5
x = 3
