First you need to get x on one side so subtract 3x from both sides which will leave you with 8=2x-20. Next add 20 to both sides to get 28=2x. Then divide everything by 2 and you should get x = 14.
Ummm i ain’t sure but you could try to figure out the recipe of the boesack soup
The sum of g and 3.
The sum of two values is added together.
g+3
You would add g to 3 since it is their sum the statement is asking for.
I hope this helps!
