Ultimately you are trying to find the value of the variable x, so you need to isolate the x meaning put all x's on one side of the equal sign and all known values on the other side of the equal sign.\r
\n" ); document.write( "\n" ); document.write( "So lets put all x's on the right by subtracting the 2x on the left from BOTH sides of the equation
\n" ); document.write( "8x+5-2x=2x-7-2x
\n" ); document.write( "Simplify by combining like terms 8x-2x is 6x on the right and 2x-2x is 0 on the left and the resulting equations becomes
\n" ); document.write( "6x+5=-7
\n" ); document.write( "Now you put the known values on the left by subtracting the 5 on the right from BOTH sides of the equation
\n" ); document.write( "6x+5-5=-7-5
\n" ); document.write( "Simplify by combining like terms 5-5 is 0 on the right and -7-5 is -12 on the left and the resulting equation becomes
\n" ); document.write( "6x=-12
\n" ); document.write( "Then we solve for x by dividing BOTH sides of the equation by 6
\n" ); document.write( "(6x)/6=12/6
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "In order for equation to remain true, what you do to one side you must do the the other side of the equal sign \n" ); document.write( "
