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!

The phrase “inequality” tells you that you will be using inequality signs, greater than, less than, greater than or equal to, or less than or equal to. Those signs look like this (not ordered) ≤ ≥ < >
So now we have to consider the speed limit 25mph, and remember s is used to represent how fast you are going. We can start be setting up 25_s and now we must determine what sign to use. Does it make sense to go faster than the speed limit? No it doesn’t, it’s a limit. what about equal to, does it make sense to go at the speed limit? Yes you can travel 25mph in a 25mph zone. So your speed will be less than or equal to 25, because you know you can’t go faster than that but you can travel at that number. So it looks like:
25 ≥ s.
If you need help understanding why I used that particular inequality sign message me for help.
From the computation done, the total kilometers that he uses last month will be 262.8 kilometers.
The total length of a trip to and from work is 14.6 kilometers and last month, Jeremiah worked 18 days.
Therefore, the kilometers that he rode his bike to and from work last month will be;
= 14.6 × 18.
= 262.8 kilometers.
