Thank you for the opportunity to help you with your question!

1. x+0.3=3.3

x=3.3-0.3

x=3

2. 8=3r-1

8+1=3r

9=3r

9/3=r

r=3

 3. 4-m/2=10

-m/2=10-4

-m/2=6

-m=6*2

m=-12

4. 6h-7=17

6h=17+7

6h=24

h=24/6

h=4 

5. 0.6g+11=5

0.6g=5-11

0.6g= -6

g=6/0.6

g=10

6. 1=2x+1/2

1-1/2=2x

1/2=2x

x=1/4 

7. 3/4=3/8x-3/2

3/4-3/2=3/8x

 -3/2=3/8x

-3/2*8/3=x

x=-4

8. 5(h-4)=8

5h-20=8

5h=8+20

5h=28

h=28/5

 9. 2(x+3)=10

2x+6=10

2x=10-6

2x=4

x=4/2

x=2

Please let me know if you need any clarification. I'm always happy to answer your questions.
