\n" ); document.write( "Let x=number of females
\n" ); document.write( "Then 360-x=number of males
\n" ); document.write( "And 0.90(360-x)=number of males that can read and write
\n" ); document.write( "0.80(360)= number of males and females that can read and write\r
\n" ); document.write( "\n" ); document.write( "Number of males that can read and write + number of females that can read and write equals 0.80(360). So our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "0.9(360-x)+180=0.8(360)
\n" ); document.write( "324-0.9x+180=288
\n" ); document.write( "504-0.9x=288 subtract 504 from both sides
\n" ); document.write( "-0.9x=288-504
\n" ); document.write( "-0.9x=-216 divide both sides by -0.9
\n" ); document.write( "x=240-------------------------------------number of females
\n" ); document.write( "360-x=360-240=120----------------------------number of males\r
\n" ); document.write( "\n" ); document.write( "ck\r
\n" ); document.write( "\n" ); document.write( "90% of the males = 0.9(120)=108
\n" ); document.write( "108+180=288
\n" ); document.write( "80% of 360=288\r
