You can put this solution on YOUR website!
In your case it would be better to solve by multiplication because the coefficients of x or y are not the same.\r
\n" ); document.write( "\n" ); document.write( "7x - 3y = -2
\n" ); document.write( "2x - 5y = -13\r
\n" ); document.write( "\n" ); document.write( "Choose either the x or y to start. I'll choose the y. The common factor between them is 15. Multiply the top by 5 and the bottom by 3.\r
\n" ); document.write( "\n" ); document.write( " 35x-15y=-10
\n" ); document.write( "-6x-15y=39\r
\n" ); document.write( "\n" ); document.write( "Switch the signs before the equals sign
\n" ); document.write( " 35x-15y=-10
\n" ); document.write( "-6x+15y=39
\n" ); document.write( "-------------
\n" ); document.write( "29x=29
\n" ); document.write( "x=1\r
\n" ); document.write( "\n" ); document.write( "Plug 1 back into x for one of the equations.
\n" ); document.write( "7(1)-3y=-2==>7-3y=-2==>-3y=-9==>y=3\r
\n" ); document.write( "\n" ); document.write( "The ordered pair answer is (1,3)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
