Question 808629: how do you solve a system of linear equations (using the addition/elimination method) if there is no lcd?

There is ALWAYS a least common multiple. (lowest common denominator is an inappropriate term in this context)
Eq. 1
Eq. 2
Multiply Eq. 1 by 
and Eq. 2 by 
Then when you add the two equations you get:
y\ =\ \gamma_1\alpha_2\ -\ \gamma_2\alpha_2)
which is a single variable linear equation in 
. Alternatively, you could use 
and 
as your multipliers so as to end up with a single variable linear equation in 
, if that's what makes your socks roll up and down.
