Hello to everyone,
I have some systems to solve in algebra. Please help me.
1) λχ+2y=λ
8y+λy=2λ
and
2) 7 + 4 = 47
--- --- ---
x-y x+y 15
3 - 2 = 3
--- --- ---
x-y x+y 5
they are fractions.
I know the --- are fractions.
Thanks.
Hello,
What are the variables ?1) λχ+2y=λ
8y+λy=2λ
For this one...2) 7 + 4 = 47
--- --- ---
x-y x+y 15
I notice that 15=5*3
So if x-y=3 and x+y=5, you will see that it works... Perhaps there is another solution.
Else put the fractions on the same denominator and solve..
