How do I solve this problem for Solving Systems of Linear Equations by Addition:
\n" ); document.write( "-10x-y= -3
\n" ); document.write( "-2x +y= -9
\n" ); document.write( "Since the y terms are both 1, add the equations.
\n" ); document.write( "-10x-y= -3
\n" ); document.write( "-2x +y= -9
\n" ); document.write( "------------- Add
\n" ); document.write( "-12x = -12
\n" ); document.write( "x = 1
\n" ); document.write( "------
\n" ); document.write( "-2*1 + y = -9
\n" ); document.write( "y = -7\r
\n" ); document.write( "\n" ); document.write( "
