Solving for y means to get that variable on one side of the equation and everything else needs to be on the opposite side of y.
We also know x is equal to 28. So, we can replace x with 28.
Now the equation will look something like 28 + 3y = 28
Now let us solve it.
28 + 3y = 28
First, subtract 28 from each side of the equation.
(28 + 3y) - 28 = 28 - 28 =
3y = 0
Now divide each side by 3.
3y / 3 = 0 / 3
y = 0/3
If a fraction has a numerator of 0, that means it's 0.
So, y is equal to 0.

Answer:
The answer is b. But you asked for the thought process so...
Step-by-step explanation:
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.
We know that
Speed = Distance/Time.
Or, Time = Distance/Speed.
So, the time taken to cover a distance of 50 miles on his first trip = 50/x hr.
And the time taken to cover a distance of 300 miles on his later trip = 300/3x hr.
= 100/x hr.
So we can clearly see that his new time compared with the old time was: twice as much.
Have a great day :)
Answer:
Hey there so this looks harder then it really is. All you need to do is this..
700x5.5%= 38.50
then times that by 4 to get your total over the 4 years.
Simple interest=154
