Algebra.Com's Answer #309160 by solver15(27)![]() ![]() You can put this solution on YOUR website! multipy -1 to the equation x-3y=4 \n" ); document.write( "your equation will be \n" ); document.write( "-x+3y=-4 \n" ); document.write( "then elimate -x with x \n" ); document.write( "-x+3y=-4 \n" ); document.write( " x+5y=-4 \n" ); document.write( "-x and x is now elimated, so the equation will be \n" ); document.write( "8y=-8, the divide both sides by 8 \n" ); document.write( "8y/8=-8/8 \n" ); document.write( "then y=-1 \n" ); document.write( "plug in -1 to the previous equation \n" ); document.write( "x-3(-1)=4 \n" ); document.write( "x+3=4, the subtract 3 form both sides of the equation \n" ); document.write( " -3 -3 \n" ); document.write( "the x=1, so your solution is (1,-1) \n" ); document.write( " |
