Step-by-step explanation:
Let's solve for x.
2y+5x=4
Step 1: Add -2y to both sides.
5x+2y+−2y=4+−2y
5x=−2y+4
Step 2: Divide both sides by 5.

Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = 
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Rate = 24*100/(400*2) = 3%
