9x-6y=-12_x+2y=0\r
\n" ); document.write( "\n" ); document.write( "=►Multiply each equation by the value that makes the coefficients of y equal. This value is found by dividing the least common multiple of the coefficients of y by the current coefficient. In this case, the least common multiple is 6.
\n" ); document.write( "9x-6y=-12_3*(x+2y=0)\r
\n" ); document.write( "\n" ); document.write( "=►Multiply each equation by the value that makes the coefficients of y equal. This value is found by dividing the least common multiple of the coefficients of y by the current coefficient. In this case, the least common multiple is 6.
\n" ); document.write( "9x-6y=-12_3*(x+2y)=3(0)\r
\n" ); document.write( "\n" ); document.write( "=►Multiply 3 by each term inside the parentheses.
\n" ); document.write( "_3*(x+2y)=0\r
\n" ); document.write( "\n" ); document.write( "=►Multiply 3 by each term inside the parentheses.
\n" ); document.write( "_(3x+6y)=0\r
\n" ); document.write( "\n" ); document.write( "=►Remove the parentheses around the expression 3x+6y.
\n" ); document.write( "_3x+6y=0\r
\n" ); document.write( "\n" ); document.write( "=►Add the two equations together to eliminate y from the system.
\n" ); document.write( "3x+6y=0_9x-6y=-12_12x =-12\r
\n" ); document.write( "\n" ); document.write( "=►Divide each term in the equation by 12.
\n" ); document.write( "x=-1\r
\n" ); document.write( "\n" ); document.write( "=►Substitute the value found for x into the original equation to solve for y.
\n" ); document.write( "9(-1)-6y=-12\r
\n" ); document.write( "\n" ); document.write( "=►Multiply 9 by each term inside the parentheses.
\n" ); document.write( "-9-6y=-12\r
\n" ); document.write( "\n" ); document.write( "=►Move all terms not containing y to the right-hand side of the equation.
\n" ); document.write( "-6y=-3\r
\n" ); document.write( "\n" ); document.write( "=►Divide each term in the equation by -6.
\n" ); document.write( "y=(1)/(2)\r
\n" ); document.write( "\n" ); document.write( "=►This is the final solution to the independent system of equations.
