Help with pre algerbra equations PLZ

Answer 1

5.4a+8.2=9.8a-2.8 subtract 9.8a from both sides

-4.4a+8.2=-2.8 subtract 8.2 from both sides

-4.4a=-11 divide both sides by 4.4

a=11/4.4

a=2.5
...

6(m-2)=12 perform indicated operations on left side...

6m-12=12 add 12 to both sides

6m=24 divide both sides by 6

m=4

...

6-m=5m+30 subtract 5m from both sides

6-6m=30 subtract 6 from both sides

-6m=24 divide both sides by -6

m=-4

Answer 2

For the first one a = 2.5. For the second one m = 4. For the third one m = -4
