Answer:
The solution of the system is (6, 9).
Step-by-step explanation:
Solve one of the variables and substitute the answer for the other variable.
Select one of the problems and solve for x.
3x+y=27
Subtract y from both sides.
3x+-y=27
Divide both sides by three.
x=1/3(-y + 27)
Multiply 1/3 by -y + 27.
x = -1/3y + 9
Replace -y/3 + 9 for x in the other problem 3x-2y=0.
3(-1/3y + 9) - 2y = 0
Multiply 3 by -y/3 + 9.
−y+27−2y=0
Add -y to -2y.
−3y+27=0
Subtract 27 from both sides of the problem.
−3y=−27
Divide both sides by −3.
y=9
Replace 9 for y in x=−1/3y+9.
x=−1/3*9+9
Multiply −1/3 times 9.
x=-3+9
Add 9 to -3.
x = 6.
x = 6, y = 9.
Yea me what do you need help with
I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
= 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
= 30 minutes
So it will take 30 minutes to finish a 5 kilometer race.
I hope the procedure is clear to you.
