I haven't done this in a long time so please bare with me.
I need to solve this system to find the percent abundance of 2 isotopes.
68.9257x + 70.9249y=69.723
x+y=1
In order to solve the system by addition/subraction one would multiply 68.9257 through the second equation, then procede to subract right? I've been doing this, but I haven't been getting the right answer...
Help...
