You can put this solution on YOUR website!
1) if two times something is 22, that something must be 11. If a+8 is 11, a must be 3. So first you divide to get rid of whatever is outside parentheses, then you add/subtract to get rod of whatever in inside parentheses.
2) 4(m-2)=4
First divide EACH side by 4 to get m-2=1. Then add 2 to each side to get m=3.
The others work the same way. Best of luck!
