Let x be the number of pounds of peanuts.
\n" ); document.write( "\"2.50x%2B4.75%2A12=4%28x%2B12%29\" simplify
\n" ); document.write( "\"2.50x%2B57=4x%2B48\" subtract 2.50x from each side, you get
\n" ); document.write( "\"57=4x-2.50x%2B48\"
\n" ); document.write( "\"57=1.50x%2B48\" subtract 48 from each side
\n" ); document.write( "\"57-48=1.50x\"
\n" ); document.write( "\"9=1.50x\" divide both sides by 1.5
\n" ); document.write( "\"6=x\" So you need 6 pounds of peanuts.
