You can put this solution on YOUR website!
Solve $\"-5%2Bx+=+20\"$
\n" ); document.write( "When you are asked to solve a problem such as this, you are being asked to find the value of x that, when added to -5 will give the result of 20.
\n" ); document.write( "You can solve this equation for x this way:
\n" ); document.write( " $\"-5%2Bx+=+20\"$ To isolate the variable, x, you must add 5 to both sides of the equation. When you do this, you are \"undoing\" the -5 so that you are left with the variable by itself on the left side of the equation.
\n" ); document.write( " $\"-5%2B5%2Bx+=+20%2B5\"$ Because $\"-5%2B5+=+0\"$ , we are left with x by itself on the left side:
\n" ); document.write( " $\"x+=+20%2B5\"$ ...and on the right side, you can see that $\"20%2B5+=+25\"$ so...
\n" ); document.write( " $\"highlight%28x+=+25%29\"$
\n" ); document.write( "To see if this is really the correct solution for x, we'll substitute $\"x+=+25\"$ into the original equation to see if both sides are equal.
\n" ); document.write( " $\"-5%2Bx+=+20\"$ Substitute $\"x+=+25%7D%0D%0A%7B%7B%7B-5%2B25+=+20\"$ and, since $\"-5%2B25+=+20\"$ or $\"25-5+=+20\"$ we have:
\n" ); document.write( " $\"20+=+20\"$ \n" ); document.write( "

\n" );
