\n" ); document.write( "find the capacity of two trucks if 8 trips of the smaller and 4 trips of the larger makes a total haul of 36 tons, and 8 trips of the larger and 4 trips of the smaller make a total haul of 48 tons. let x= smaller and y= larger
\n" ); document.write( "

With x being the smaller truck's capacity, and y the larger truck's capacity, we get:
\n" );
document.write( "8x + 4y = 36_____2(4x + 2y) = 2(18)______4x + 2y = 18 ------ eq (i)
\n" );
document.write( "4x + 8y = 48 ------- eq (ii)
\n" );
document.write( "- 6y = - 30 ------ Subtracting eq (ii) from eq (i)
\n" );
document.write( "y, or larger truck's capacity = , or  tons\r
\n" );
document.write( "\n" );
document.write( "4x + 2(5) = 18 ------ Substituting 5 for y in eq (i)
\n" );
document.write( "4x + 10 = 18
\n" );
document.write( "4x = 18 - 10
\n" );
document.write( "4x = 8
\n" );
document.write( "x, or smaller truck's capacity = , or  tons
\n" );
document.write( "You can do the check!!
