Question 169981: Hi, Can you please help?
.
Can you please give me some math problems for my homework?
I need to solve systems of equations
.
Can you please give some systems of equations that I could solve?
.
Keep in mind that I have to solve these equations with both the substitution, and elimination method
.
I would like some easy problems ( with answers with whole numbers, like ( 4,5 ) and ( -1, 8 ) )
.
I would like some medium problems ( with answers with nice fractions such as ( 1/2, - 3/4 ) and ( 2/5, 1/10 )
.
I would like hard problems ( with answers with fractions like ( 43/99, 44/199) and ( - 309/299, 87/77 )
.
I need to at least have 20 - 30 problems. So I need at least 20 people to submit one, or ten submit two, and so forth, ( or if one person could send a lot of them)
.
It doesn't matter if I get 1000(exaggeration) problems, I just need a good number of them.
.
Please send me the answers to my email at Electrified_Levi@yahoo.com
.
Also, if some can give some easy 3 variable equations with whole numbers, or even medium difficulty
.
Thanks
