I have a word problem and not sure how to set up the equation:
\n" ); document.write( "A furniture company needs to ship 96 sofas and 57 chairs
\n" ); document.write( "They have small trucks and large trucks
\n" ); document.write( "Each small truck is designed to hold 4 sofas and 3 chairs
\n" ); document.write( "Each large truck is designed to hold 12 sofas and 6 chairs
\n" ); document.write( "Let x represent the number of small trucks needed
\n" ); document.write( "Let y represent the number of large trucks needs.
\n" ); document.write( "Write the system of equation that represents this situation then solve.
\n" ); document.write( ":
\n" ); document.write( "Sofa equation
\n" ); document.write( "4x + 12y = 96
\n" ); document.write( ":
\n" ); document.write( "Chair equation
\n" ); document.write( "3x + 6y = 57
\n" ); document.write( ":
\n" ); document.write( "Solve by elimination: Multiply the chair equation by 2, subtract sofa equation
\n" ); document.write( "6x + 12y = 114
\n" ); document.write( "4x + 12y = 96
\n" ); document.write( "---------------subtracting eliminates y, solve for x
\n" ); document.write( "2x + 0y = 18
\n" ); document.write( "x = 18/2
\n" ); document.write( "x = 9 small trucks
\n" ); document.write( ":
\n" ); document.write( "Find y
\n" ); document.write( "using sofa equation, substitute 9 for x
\n" ); document.write( "4(9) + 12y = 96
\n" ); document.write( "36 + 12y = 96
\n" ); document.write( "12y = 96 - 36
\n" ); document.write( "12y = 60
\n" ); document.write( "y = 60/12
\n" ); document.write( "y = 5 large trucks
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the chair equation:
\n" ); document.write( "3(9) + 6(5) =
\n" ); document.write( "27 + 30 = 57 as required
\n" ); document.write( ":
\n" ); document.write( "Hope this helped & Merry Christmas!!\r
