solve the following using the substitution method and the elimination method.
\n" ); document.write( ":
\n" ); document.write( "4x+3y=48
\n" ); document.write( "3x+2y=34
\n" ); document.write( ":
\n" ); document.write( "Use the 2nd equation for substitution
\n" ); document.write( "3x + 2y = 34
\n" ); document.write( "2y = -3x + 34
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "y = \"-3%2F2\"x + \"34%2F2\"
\n" ); document.write( "y = -1.5x + 17
\n" ); document.write( ":
\n" ); document.write( "Substitute (-1.5x+17) for y in the 1st equation
\n" ); document.write( "4x + 3(-1.5x + 17) = 48
\n" ); document.write( "4x - 4.5x + 51 = 48
\n" ); document.write( "4x - 4.5y = 48 - 51
\n" ); document.write( "-.5x = -3
\n" ); document.write( "x has to be positive, multiply both sides by -1
\n" ); document.write( ".5x = 3
\n" ); document.write( "x = \"3%2F.5\"
\n" ); document.write( "x = 6
\n" ); document.write( "find y using y = -1.5x+17
\n" ); document.write( "y = -1.5(6) + 17
\n" ); document.write( "y = -9 + 17
\n" ); document.write( "y = +8
\n" ); document.write( "Check solutions in the 2nd equation; 3x+2y=34
\n" ); document.write( "3(6) + 2(8) = 34
\n" ); document.write( "18 + 16 = 34
\n" ); document.write( "34 = 34; confirms our solutions
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "By elimination
\n" ); document.write( "4x+3y=48
\n" ); document.write( "3x+2y=34
\n" ); document.write( "Multiply the 1st equation by 2, and the 2nd equation by 3
\n" ); document.write( "8x + 6y = 96
\n" ); document.write( "9x + 6y = 102
\n" ); document.write( "------------------subtraction eliminates y, find x
\n" ); document.write( "-1x = -6
\n" ); document.write( "x = 6; mult by -1
\n" ); document.write( ":
\n" ); document.write( "You can find y using either equation, replacing x with 6
\n" ); document.write( "
\n" );
