You get the answer by looking at the problem and if one of the parts says k= than you can substitute it into the other problem and then you do the math and find what K equals. Then you need to find j so you put the answer for k in one problem and solve. You would then get j and the problem is done. This is a one solution problem because it has one awnsor and it makes sense.
See John this is a substitution method. It is also a one solution.
So do you understand it so far.
I do thanks
3m + n = 30 2m + n=20 m = 10 n = 0
This is an elimination problem because you can either add or subtract something together so that you get 0. When you do that you need to know to add or subtract then when you do that you can do the math and divide 5 by 50 and you get m = 10. Then to get n you need to pick one of the problems then put m in for m and then do the math and you get n.
John this is an elimination
A no solution problem is a problem were the numbers you get as an answer don't make sense.
An infinite solution is where a solution is all zeros. When this occurs there is an infinite amount of solutions because all of the numbers you get are the same.
Does this help you better understand solving linear equations
