Algebra.Com's Answer #224129 by OmniMaestra(21)![]() ![]() You can put this solution on YOUR website! So far you are doing great but you aren't finished yet. Now that you've solved both equations for y you can use the transitive property that says \n" ); document.write( "if a=y and y=b then a=b so... \n" ); document.write( "if \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve for x\r \n" ); document.write( "\n" ); document.write( "subtract 4 from both sides:-------> \n" ); document.write( "\n" ); document.write( "subtract x from both sides------> \n" ); document.write( "\n" ); document.write( "simplify-------------------------> \n" ); document.write( "\n" ); document.write( "Multiply both sides by -3---------> \n" ); document.write( "\n" ); document.write( "now substitute the -3 into one of the original equations\r \n" ); document.write( "\n" ); document.write( "-y=-x+5 \n" ); document.write( "-y=-(-3)+5 \n" ); document.write( "-y=8 \n" ); document.write( "y=-8 \n" ); document.write( " |
