7x+9y=26----------(1)
\n" ); document.write( "x=32-6y-----------(2)
\n" ); document.write( "Solve for y and x
\n" ); document.write( " sustitute the value of x given in equation 2 to equation 1
\n" ); document.write( "
\n" ); document.write( " 7x+9y=26
\n" ); document.write( "7(32-6y)+9y = 26\r
\n" ); document.write( "\n" ); document.write( "224-42y+9y = 26\r
\n" ); document.write( "\n" ); document.write( "224-33y= 26\r
\n" ); document.write( "\n" ); document.write( "224-26-33y = 26-26\r
\n" ); document.write( "\n" ); document.write( "198-33y= 0\r
\n" ); document.write( "\n" ); document.write( "198-33y+33y = 0+33y\r
\n" ); document.write( "\n" ); document.write( "198 = 33y\r
\n" ); document.write( "\n" ); document.write( "33y/33y = 198/33\r
\n" ); document.write( "\n" ); document.write( "y = 6
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( " x = 32-6y
\n" ); document.write( " = 32-6(6)
\n" ); document.write( " = 32-36
\n" ); document.write( " = -4
\n" ); document.write( " hence x = -4 and y = 6 is the solution for the system of equation
\n" ); document.write( " \n" ); document.write( "
\n" );
