Algebra.Com's Answer #240098 by stanbon(75887) ![]() You can put this solution on YOUR website! if i am teatching a class how would i teach them how to solve \n" ); document.write( "3-5(x+2)=3(x+1)+6\r \n" ); document.write( "\n" ); document.write( "------------------- \n" ); document.write( "Your Problem: \n" ); document.write( "3-5(x+2)=3(x+1)+6 \n" ); document.write( "Explain the distributive law \n" ); document.write( "and apply it to the parentheses \n" ); document.write( "on the left and on the right side \n" ); document.write( "to get: \n" ); document.write( "3-5x-10 = 3x+3+6 \n" ); document.write( "----- \n" ); document.write( "Simplify each side by combining \"like\" terms. \n" ); document.write( "-5x-7 = 3x+9 \n" ); document.write( "----- \n" ); document.write( "Add 5x to both sides to get: \n" ); document.write( "-7 = 8x+9 \n" ); document.write( "Subtract 9 from both sides to get: \n" ); document.write( "8x = -16 \n" ); document.write( "Divide both sides by 8 to get: \n" ); document.write( "x = -2 \n" ); document.write( "----------------------------------------------- \n" ); document.write( "Teach the students how to check their answers so \n" ); document.write( "they will know if their answers are correct. \n" ); document.write( "3-5(x+2)=3(x+1)+6 \n" ); document.write( "Substitute -2 for \"x\": \n" ); document.write( "3-(-2+2) = 3(-2+1)+6 \n" ); document.write( "3-0 = 3(-1)+6 \n" ); document.write( "3 = -3+6 \n" ); document.write( "3 = 3 \n" ); document.write( "===================== \n" ); document.write( "Tell the students this means they have found \n" ); document.write( "a numerical value that makes the original \n" ); document.write( "equal true when it is substituted for the \n" ); document.write( "letter \"x\". \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=============== \n" ); document.write( " |
