\n" ); document.write( "10x-2y=35. If you multiply the top equation by 4, by which number will you multiply the bottom equation?

Multiply by 12 or - 12, but that's very INEFFICIENT though.

document.write( "If it matters, the best way to eliminate y is to MULTIPLY eq (ii) by - 3 to get eq (iii). Then, ADD eqs (iii) & (i). \n" );
