Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!

Step-by-step explanation:
I got it right on edg
Answer:
B/ x=4
Step-by-step explanation:
Just take 2x to another side to be neg-, the same thing with 4 , then divide it both sides by 4 to get the answer.
Answer:
I got C because A and B are too small for the standard division to be a mean of 80% and the number also cannot be 50% or higher because it could bring the median lower and or higher
