How to do I do solving systems of equations by elimination

Mathematics

Andre45 [30]3 years ago

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!

In the same way,

6  builder will take  (\frac{54}{9}*6)  days to complete a house,

i.e.
