Algebra.Com's Answer #81340 by brandonpark2889(31)![]() ![]() ![]() You can put this solution on YOUR website! 20-6x= -4(2x-1)+2\r \n" ); document.write( "\n" ); document.write( "and\r \n" ); document.write( "\n" ); document.write( "3(5x-9)-x= -12+4x\r \n" ); document.write( "\n" ); document.write( "i've answered the first problem already but i'd like to see if you end up with the same answer but i seem to not be able to answer the second problem. Thank you for your time and i greatly appreciate your help! \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Okay, i see. It can be a little difficult, but try to follow where i'm going. If you have questions, email me at brandonpark2889@msn.com. \n" ); document.write( "1st one: 20-6x = -4(2x-1)+2. \n" ); document.write( "First, use the distributive property to multiply -4 to 2x and -1, turns out to be 20-6x = -8x+4+2. \n" ); document.write( "Secondly, combine all the like terms, which is +4 and +2. 20-6x = -8x+6. \n" ); document.write( "Third, subtract 6 on each side, using subtractive property of equation/equality, ending up with: 14-6x = -8x. \n" ); document.write( "Fourth, add 6x on each side, using additive property of equation/equality, ending up with: 14 = -2x. \n" ); document.write( "Fifth, divide -2 on each side, using division property of equation/equality, ending up with x = -7. \n" ); document.write( "Check by putting -7's instead of x's, and see if two sides are equal. \n" ); document.write( "I know, it's little complicated, at least how i wrote it down. But if you have problems, feel free to email me. \n" ); document.write( "2nd one: 3(5x-9)-x= -12+4x. \n" ); document.write( "First, again use the distributive property to multiply 3 to 5x and -9, turns out to be 15x - 27 - x = -12 + 4x. \n" ); document.write( "Second, combine all the like terms, which is 15x and -x: 14x - 27 = -12 + 4x. \n" ); document.write( "Third, add 27 to each side, using additive property of equation/equality, which equals: 14x = 15 + 4x. \n" ); document.write( "Fourth, subtract 4x to each side, using subtractive property of equation/equality, which is: 10x = 15. \n" ); document.write( "Finally, divide 10 on each side, using division property of equation/equality, which x = 1 \n" ); document.write( "I hope that you gotten what i have explained. again, feel free to email! \n" ); document.write( "_______\r \n" ); document.write( "\n" ); document.write( "Good luck; math is more than just memorizing! \n" ); document.write( " |
