Algebra.Com's Answer #102526 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Solving equations is basically \"undoing\" what was done to the x. In this case, you need to \"undo\" additon of +3 by subtracting 3 from each side.\r \n" ); document.write( "\n" ); document.write( "2x+3=8 \n" ); document.write( "2x+3-3 = 8-3 \n" ); document.write( "2x= 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Next, to \"undo\" multiplication by 2, divide both sides by 2. \n" ); document.write( "x=5/2 or 2.5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For a detailed explanation of this see my website by clicking on my tutor name \"rapaljer\" anywhere in algebra.com. Take the first link which is \"Basic, Intermediate, or College Algebra: One Step at a Time.\" Click on \"Basic Algebra\", then \"Chapter 1\", and look for Section 1.08 Basic Equation Solving. MY explanations here are for students who don't understand the traditional textbooks. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 \n" ); document.write( " |
