\"7x-2%28x%2B2%29-3=4x%2B5\": Original problem
\n" ); document.write( "\"7x-2x%2B2-3=4x%2B5\": Your first error. \"-2%28x%2B2%29=-2x-4\" (distributive property), so you should have \"7x-2x%2B4-3=4x%2B5\"
\n" ); document.write( "\"7x-2x%2B1=4x%2B5\": The next thing I notice is that you are just moving terms back and forth across the equal sign. What you need to do is add or subtract from both sides of the equation to make a zero result on one side and the term, with the opposite sign, appear on the other.
\n" ); document.write( ":
\n" ); document.write( "\"7x-2x-4x%2B1-1=4x-4x%2B5-1\". I subtracted 4x from both sides and 1 from both sides.
\n" ); document.write( ":
\n" ); document.write( "\"x=4\": 7 minus 2 minus 4 is 1, 1 minus 1=0, 4x minus 4x = 0, and 5 minus 1 = 4
