Algebra.Com's Answer #594215 by rothauserc(4718) You can put this solution on YOUR website! y = [(2*(x+10) - 18) * (1/2)] - x \n" ); document.write( "now we have y = 1 and we are asked to solve for x \n" ); document.write( "1 = [(2*(x+10) - 18) * (1/2)] - x \n" ); document.write( "1 = (2x + 20 - 18) * (1/2) - x \n" ); document.write( "1 = x + 1 - x \n" ); document.write( "1 = 1 \n" ); document.write( "therefore any number that is picked will yield a result of 1 \n" ); document.write( " \n" ); document.write( " |
