Hello, \n" ); document.write( "I'll help you on the first one--let's see if you can figure out the others. \n" ); document.write( "28+x=7-2x \n" ); document.write( "First subtract x from both sides to get: \n" ); document.write( "28=7-3x \n" ); document.write( "Now subtract 7 from both sides to get: \n" ); document.write( "21=-3x \n" ); document.write( "Now divide -3 into both sides to result in: \n" ); document.write( "x=-7 \n" ); document.write( "We can check to see if this is correct by plugging the answer in. \n" ); document.write( "(Hint: What we try to do in these equations is get the variable, in this case \"x\" all by itself. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
