I can't wrap my brain around this word problem.

\n" ); document.write( "----------------
\n" ); document.write( "Quantity Equation: s + a = 3000
\n" ); document.write( "Percentage Equatio: 0.10s + 0.15a = 0.12*3000
\n" ); document.write( "---------------------------------
\n" ); document.write( "Rearrange the equations for elimination:
\n" ); document.write( "10s + 10a = 30000
\n" ); document.write( "10s + 15a = 12*3000
\n" ); document.write( "----------------
\n" ); document.write( "Subtract the 1st from the 2nd to get:
\n" ); document.write( "5a = 6000
\n" ); document.write( "a = 1200 (# of agriculture division layoffs)
\n" ); document.write( "s = 1800 (# of aerospace division layoffs)
