Given:
\n" ); document.write( ".
\n" ); document.write( "\"6-5%283x-3%29=-54\"
\n" ); document.write( ".
\n" ); document.write( "First do the distributed multiplication of -5 times each of the terms inside the parentheses.
\n" ); document.write( ".
\n" ); document.write( "When you multiply -5 times 3x you get -15x. And when you multiply -5 times -3 you get +15.
\n" ); document.write( "Substituting these multiplications into the given problem converts it to:
\n" ); document.write( ".
\n" ); document.write( "\"6+-+15x+%2B+15+=+-54\"
\n" ); document.write( ".
\n" ); document.write( "On the left side combine the constants +6 and +15 to get +21 which reduces the equation to:
\n" ); document.write( ".
\n" ); document.write( "\"-15x+%2B+21+=+-54\"
\n" ); document.write( ".
\n" ); document.write( "Get rid of the +21 on the left side by adding -21 to both sides. (This is the same as
\n" ); document.write( "subtracting 21 from both sides). When you do this addition, on the left side the +21 and -21
\n" ); document.write( "combine to cancel out. On the left side the -54 and -21 combine to -75. So the resulting
\n" ); document.write( "equation is:
\n" ); document.write( ".
\n" ); document.write( "\"-15x+=+-75\"
\n" ); document.write( ".
\n" ); document.write( "You can get rid of the minus signs by multiplying both sides of the equation by minus 1 to get:
\n" ); document.write( ".
\n" ); document.write( "\"15x+=+75\"
\n" ); document.write( ".
\n" ); document.write( "Finally, solve for x by dividing both sides of this equation by 15 to get:
\n" ); document.write( ".
\n" ); document.write( "\"x+=+75%2F15+=+5\"
\n" ); document.write( ".
\n" ); document.write( "Now that you know that x = 5, you can check the problem by starting with:
\n" ); document.write( ".
\n" ); document.write( "\"6-5%283x-3%29=-54\"
\n" ); document.write( ".
\n" ); document.write( "Then substitute 5 for x to get:
\n" ); document.write( ".
\n" ); document.write( "\"6-5%28%283%2A5%29-3%29=-54\"
\n" ); document.write( ".
\n" ); document.write( "Multiply the 3 times 5 to get:
\n" ); document.write( ".
\n" ); document.write( "\"6-5%2815-3%29=-54\"
\n" ); document.write( ".
\n" ); document.write( "Within the parentheses the 15 and -3 combine to 12:
\n" ); document.write( ".
\n" ); document.write( "\"6-5%2812%29=-54\"
\n" ); document.write( ".
\n" ); document.write( "The -5 times 12 results in -60 and this reduces the equation to:
\n" ); document.write( ".
\n" ); document.write( "\"6-60=-54\"
\n" ); document.write( ".
\n" ); document.write( "The left side terms combine to -54 so the equation further reduces to:
\n" ); document.write( ".
\n" ); document.write( "\"-54+=+-54\"
\n" ); document.write( ".
\n" ); document.write( "and this, of course, is true. So our answer checks, and x = 5 is the answer.
