Algebra.Com's Answer #215058 by wise1(2) You can put this solution on YOUR website! -9 - (-2.3)= -9 +(?) \n" ); document.write( "for this question, let's replace the question mark with x. \n" ); document.write( "-9 - (-2.3)= -9 +(x) \n" ); document.write( "next, we will open the brackets. remember, (-)*(-)=+ \n" ); document.write( "-9+2.3 = -9 + x \n" ); document.write( "now we have to solve for x, this means we want x to be alone on one side of the = sign. if you move anything from one side of an = sign, it changes from - to+ or from + to -. \n" ); document.write( "-9 +2.3 +9 =x \n" ); document.write( "2.3=x , which is the same as \n" ); document.write( "x=2.3 \n" ); document.write( "now all we have to do is replace the ? with 2.3 \n" ); document.write( "-9 - (-2.3)= -9 +(2.3) \n" ); document.write( "and voila, we're all done \n" ); document.write( " |
