2. 4n-9=-9

3. 1-r=-5

4. -4+x/2=6

5. n/2+5=3

6. -7+4r=-15

7. m-13/2=-8

8. 9+n/4=15

PLEASE GIVE ACTUAL ANSWERS INSTEAD OF TELLING ME TO LOOK IT UP AND PLEASE SHOW WORK FOR EACH PROBLEM!

Step-by-step explanation:

1)  r/10+4+5=

   r/10+9-9=0-9

   r/10=-9

   r/10*10=-9*10

   r=90

2) 4n-9=-9

    4n-9+9=-9+9

    4n/4=0/4

    n=0

3) 1-r=-5

    -1-1-r=-5

    -r=-5

    r=5

4) -4+x/2=6

   -4+1/2x=6

   -8+x=12

    x=12+8

5)  n/2+5=3

    1/2n+5=3

    n+10=6

    n=6-10

   n=-4

6)   -7+4r=-15

    4r=-15+7

     4r=-8

      r=-2

7)   m-13/2=-8

   m-6.5=-8

   m=-1.5

8)   9+n/4=15

    9+1/4x=15

  36+x=60

   x=60-36

    x=24
