3x+8y=22 and
\n" ); document.write( "10x-2y=16\r
\n" ); document.write( "\n" ); document.write( "Let us find the value of y in terms of x from the second equation so that we can substitute it in the first one.\r
\n" ); document.write( "\n" ); document.write( "10x-2y=16
\n" ); document.write( "10x-16=2y{divide everything by 2 now}
\n" ); document.write( "5x-8=y
\n" ); document.write( "y=5x-8\r
\n" ); document.write( "\n" ); document.write( "Now, substitute this value of y in the first equation :\r
\n" ); document.write( "\n" ); document.write( "3x + 8y = 22
\n" ); document.write( "3x + 8(5x-8) = 22
\n" ); document.write( "3x + 40x-64 = 22
\n" ); document.write( "43x - 64 = 22
\n" ); document.write( "43x =22+64
\n" ); document.write( "43x =86
\n" ); document.write( "x = 86/43 = 2
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "Now substitute the value of x in the following equation to get y.
\n" ); document.write( "y=5x-8
\n" ); document.write( "y=5(2)-8
\n" ); document.write( "y=10-8=2\r
\n" ); document.write( "\n" ); document.write( "Ans. Both the values of x and y are 2.
