You can put this solution on YOUR website!
As long as you do the exact same thing to both
\n" ); document.write( "sides of an equation, the equation is still true
\n" ); document.write( "8x + 9 = 25
\n" ); document.write( "4x + 10 = 30
\n" ); document.write( "Solve using the principles together
\n" ); document.write( "-8x - 24 = -29 1/3
\n" ); document.write( "3x + 10x + 91
\n" ); document.write( "3x - 18 = 9
\n" ); document.write( "-----------------
\n" ); document.write( "\"8x+%2B+9+=+25\"
\n" ); document.write( "Subtract \"9\" from both sides
\n" ); document.write( "\"8x+=+25+-+9\"
\n" ); document.write( "\"8x+=+16\"
\n" ); document.write( "Divide both sides by \"8\"
\n" ); document.write( "\"x+=+2\" answer
\n" ); document.write( "----------------
\n" ); document.write( "\"4x+%2B+10+=+30\"
\n" ); document.write( "Subtract \"10\" from both sides
\n" ); document.write( "\"4x+=+30+-+10\"
\n" ); document.write( "\"4x+=+20\"
\n" ); document.write( "Divide both sides by \"4\"
\n" ); document.write( "\"x+=+5\" answer
\n" ); document.write( "----------------
\n" ); document.write( "\"-8x+-+24+=+-29+1%2F3\"
\n" ); document.write( "First, what is 29 1/3? How many 1/3's are there in 29?
\n" ); document.write( "The answer is \"3%2A29+=+87\" 1/3's. Add 87 1/3's and
\n" ); document.write( "1/3 to get 88 1/3's. So, the equation becomes
\n" ); document.write( "\"-8x+-24+=+-%2888%2F3%29\"
\n" ); document.write( "Now multiply both sides by \"-1\"
\n" ); document.write( "\"8x+%2B+24+=+88%2F3\"
\n" ); document.write( "Multiply both sides by \"3\"
\n" ); document.write( "\"24x+%2B+72+=+88\"
\n" ); document.write( "Subtract \"72\" from both sides
\n" ); document.write( "\"24x+=+16\"
\n" ); document.write( "Divide both sides by \"24\"
\n" ); document.write( "\"x+=+16%2F24\"
\n" ); document.write( "Now multiply the right side by \"%281%2F8%29+%2F+%281%2F8%29\" which is
\n" ); document.write( "actually \"1\" and multiplying by \"1\" does not change
\n" ); document.write( "anything
\n" ); document.write( "\"x+=+%28%281%2F8%29%2A%2816%29%29+%2F+%28%281%2F8%29%2A%2824%29%29\"
\n" ); document.write( "\"x+=+2%2F3\" answer
\n" ); document.write( "check the answer:
\n" ); document.write( "\"-8x+-+24+=+-29+1%2F3\"
\n" ); document.write( "\"-8%2A%282%2F3%29+-+24+=+-29+1%2F3\"
\n" ); document.write( "\"-%2816%2F3%29+-+24+=+-%2888%2F3%29\"
\n" ); document.write( "\"16%2F3+%2B+24+=+88%2F3\"
\n" ); document.write( "multiply both sides by \"3\"
\n" ); document.write( "\"16+%2B+72+=+88\"
\n" ); document.write( "\"88+=+88\"
\n" ); document.write( "You can, and should check all of your answers like this,
\n" ); document.write( "unless you don't have time, like during a test.
\n" ); document.write( "That's all I have time for, good luck.
