Answer:
x= -1
Step-by-step explanation:
1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.
2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.
3. That will leave you with 14x= -14.
4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.
5. That will leave you with x= -1. That is your final answer.

The smallest whole number we can use to multiply each term in order to eliminate the fractions is 4:
Multiplying each side of the equation by 4, we have:
Multiplying each side of the equation by 4, we have:

Answer:
, 
Step-by-step explanation:
Given
A motorboat takes 5 hours to travel 200 miles upstream and 4 hours to go downstream
Suppose the speed of motorboat in still water and rate of current be x and y respectively.
during upstream

During downstream

Add (i) and (ii) we get


Thus, the speed of boat in still water is
and rate of current is 
-167, because if you solve -18-x=9, x will be equal to -27. When you put -27 in place of the x in -5+6x, you get -167. Have a nice day!
