Answer:
Pic 1: 
Pic 2: 
Step-by-step explanation:
<u>Picture 1:</u>
<u />
First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
<u>Picture 2:</u>
<u />
<u />
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
