You can put this solution on YOUR website!
4x + 8 = –4
\n" ); document.write( "Read it like this:
\n" ); document.write( "\"If I add 8 to 4 times an unknown quantity, the answer is -4.\"
\n" ); document.write( "It is solve with rules of algebra which say: Anything I do to
\n" ); document.write( "one side of an equation, I must do to the other side
\n" ); document.write( "First, subtract 8 from both sides
\n" ); document.write( "4x + 8 - 8 = -4 -8
\n" ); document.write( "do the subtraction
\n" ); document.write( "4x = -12
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "\"%284x%29%2F4+=+%28-12%29%2F4\"
\n" ); document.write( "do the division
\n" ); document.write( "\"x+=+-3\" this is the solution
\n" ); document.write( "You can check it by putting it back into equation
\n" ); document.write( "4*(-3) + 8 = -4
\n" ); document.write( "-12 + 8 = -4
\n" ); document.write( "-4 = -4
\n" ); document.write( "checks OK\r
