Algebra.Com's Answer #87947 by stanbon(75887) ![]() You can put this solution on YOUR website! Solve for the indicated variable. \n" ); document.write( "1. 5x + y = 8;y <--- wanting to say do what?? \n" ); document.write( "Equation: \n" ); document.write( "5x+y = 8 \n" ); document.write( "Subtract 5x from both sides to get: \n" ); document.write( "y = -5x+8 \n" ); document.write( "----------------------- \n" ); document.write( "And this one. \n" ); document.write( "Directions: \n" ); document.write( "Tell which equation you would use to isolate a variable. Explain your reasoning. \n" ); document.write( "3x - y = 5 \n" ); document.write( "2x + y = 0 \n" ); document.write( "---------------- \n" ); document.write( "Solve the 2nd equation for \"y\" to get: \n" ); document.write( "y = -2x \n" ); document.write( "The reason for using the 2nd equation is nothing \n" ); document.write( "more than that the result is simpler. \n" ); document.write( "There is no magic involved. \n" ); document.write( "=================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
