Question 1128603
You want to get rid of the y by elimination in the system below: x-6y=35; 
10x-2y=35. If you multiply the top equation by 4, by which number will you multiply the bottom equation?
-----------
x-6y = 35 times 4 ----> 4x-24y = 140
10x-2y = 35 times ? --> Ax-24y = 35B
================
I would multiply the 2nd eqn by 3, and use the 1st eqn as is.
