Algebra.Com's Answer #337911 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! I do not understand how to do these types of equations at all.Here is an example problem. 7(2x-4)-(10-3x)Can you explain how to solve this? \n" ); document.write( "--------------- \n" ); document.write( "It's not an equation, there's no equal sign. \n" ); document.write( "So, there's nothing to solve. \n" ); document.write( "---------- \n" ); document.write( "You should say, but I suppose you want to simplify it. \n" ); document.write( "7(2x-4)-(10-3x) \n" ); document.write( "----- \n" ); document.write( "Look at the first term, 7(2x-4) \n" ); document.write( "Multiply by the 7. Is that a mystery? \n" ); document.write( "7(2x-4) = 7*2x - 7*4 = 14x-28 \n" ); document.write( "----- \n" ); document.write( "14x-28 - (10-3x) \n" ); document.write( "= 14x-28 -1*10 -1*(-3x) \n" ); document.write( "= 14x-28 - 10 + 3x \n" ); document.write( "= 17x - 38\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
