• 6.3x + 7.2y = 5.4
• 5.6x + 6.4y = 4.8
a) Multiply both equations by 10.
b) Multiply both equations by 100.
c) Divide the first equation by 9.
d) Divide the second equation by 8.
=================
I would multiply by 10 to eliminate fractions, as in a.
-------------
Doing both c & d is good, too.
"best" is not clearly defined math term.
