How to do I do solving systems of equations by elimination

Mathematics

If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16        3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16    -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24.    24-16=8.    3x12=36     36-8=28    And, You're done!

Minchanka [31]
C(x) = 300.

Our question becomes simple: 300 = x^2-40x+610

x^2-40x+610-300 = 0
x^2-40x+310 = 0

Now find the value for x with either the quadratic formula or by factorization.

Let me know how it goes. Giving the full answer won’t help you improve

Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.

Step-by-step explanation:

For this case, the first thing you should know is:

d: v * t

Where,

d: distance

v: speed

t: time

To go to school by bus we have:

d = 45 * t

To return from school we have:

d = 2.5 * (1-t)

how the distance is the same:45 * t = 2.5 * (1-t)
