You can put this solution on YOUR website!
Do not get confused with that inequality sign(<,>), you solve the problem just as if it was an = sign.\r
\n" ); document.write( "\n" ); document.write( "4x + 12 >= 36 + 4
\n" ); document.write( "We first add the 36+4=40;
\n" ); document.write( "\"4x%2B12%3E=40\"
\n" ); document.write( "Now we subtract 12 from both sides;
\n" ); document.write( "\"4x%2B12-12%3E=40-12\"
\n" ); document.write( "\"4x%3E=28\"
\n" ); document.write( "Now divide both sides by 4;
\n" ); document.write( "\"4x%2F4%3E=28%2F4\"
\n" ); document.write( "\"x%3E=7\"\r
\n" ); document.write( "\n" ); document.write( "8z + 4z < 6z - 12
\n" ); document.write( "First we want to add the 8z+4z, which we are able to do because they are like terms.8z+4z=12z
\n" ); document.write( "12z<6z-12
\n" ); document.write( "Now we want to get the variable z on one side. So we will subtract 6z from both sides.
\n" ); document.write( "12z-6z<6z-12-6z
\n" ); document.write( "6z<-12
\n" ); document.write( "Divide both sides by 6;
\n" ); document.write( "\"6z%2F6%3C-12%2F6\"
\n" ); document.write( "z<-2
\n" ); document.write( "Don't forget to check the answer.
\n" ); document.write( "1. \"4%287%29%2B12%3E=40\"
\n" ); document.write( " \"28%2B12%3E=40\"
\n" ); document.write( " \"40%3E=40\"\r
\n" ); document.write( "\n" ); document.write( "2. 12(-2)<6(-2)-12
\n" ); document.write( " -24<-12-12
\n" ); document.write( " -24<-24\r
\n" ); document.write( "\n" ); document.write( "Hope this helps
