Algebra.Com's Answer #37660 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! 6.2(x - 15.1) = 9.3(-x - 3.2) \n" ); document.write( ": \n" ); document.write( "Mult what's inside the brackets first: \n" ); document.write( "6.2x - 93.62 = -9.3x - 29.76 \n" ); document.write( ": \n" ); document.write( "If decimals bother you, mult eq by 100 to get rid of them, \n" ); document.write( "620x - 9362 = -930x - 2976 \n" ); document.write( ": \n" ); document.write( "Perform the necessary operations to get the variable on the left and the numerical values on the right: \n" ); document.write( ": \n" ); document.write( "Add 9362 to both sides: \n" ); document.write( "620x = -930x - 2976 + 9362 \n" ); document.write( ": \n" ); document.write( "Add 930x to both sides, add the numerical values \n" ); document.write( "620x + 930x = + 6386 \n" ); document.write( ": \n" ); document.write( "Add the x's \n" ); document.write( "1550x = 6386 \n" ); document.write( ": \n" ); document.write( "Divide both sides by 1550 \n" ); document.write( "x = 6386/1550 \n" ); document.write( ": \n" ); document.write( "x = 4.12 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check our solution by substituting 4.12 for x in the original equation: \n" ); document.write( "6.2(x - 15.1) = 9.3(-x - 3.2) \n" ); document.write( ": \n" ); document.write( "6.2(4.12 - 15.1`) = 9.3(-4.12 -3.2) \n" ); document.write( ": \n" ); document.write( "Do the math inside the brackets and you have: \n" ); document.write( "6.2(-10.98) = 9.3(-7.32) \n" ); document.write( ": \n" ); document.write( "-68.076 = -68.076 confirms our solution of x = 4.12. \n" ); document.write( ": \n" ); document.write( "A good idea to always check your solution in the original equation. \n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
