-3x-4y = -22
\n" ); document.write( "5x - 8y = -22
\n" ); document.write( ":
\n" ); document.write( "Multiply the 1st equation by -2
\n" ); document.write( "6x + 8y = 44
\n" ); document.write( "5x - 8y = -22
\n" ); document.write( "----------------adding eliminates y, find x
\n" ); document.write( "11x = 22
\n" ); document.write( "x = \"22%2F11\"
\n" ); document.write( "x = 2
\n" ); document.write( ":
\n" ); document.write( "Find y using the 2nd equation
\n" ); document.write( "5(2) - 8y = -22
\n" ); document.write( "10 - 8y = -22
\n" ); document.write( "-8y = -22 - 10
\n" ); document.write( "-8y = -32
\n" ); document.write( "Multiply both sides by -1
\n" ); document.write( "8y = 32
\n" ); document.write( "y = \"32%2F8\"
\n" ); document.write( "y = 4
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the 1st equation
\n" ); document.write( "-3x - 4y = -22
\n" ); document.write( "-3(2) - 4(4) = -22
\n" ); document.write( "-6 - 16 = -22; confirms our solutions
\n" ); document.write( " \n" ); document.write( "
