You can put this solution on YOUR website!
In this problem, you first need to distribute the negative sign across the parentheses, which changes the problem to $\"10x+-+2x+-+3+=+21\"$ .\r
\n" ); document.write( "\n" ); document.write( "Now that you have done that, all equations are basically solved the same way:\r
\n" ); document.write( "\n" ); document.write( "1. Combine like terms. In this case, your equation changes to $\"8x+-+3+=+21\"$ .\r
\n" ); document.write( "\n" ); document.write( "2. Get everything with an x on one side and everything without an x on the other side of the equal sign. In this equation, you need to move -3 to the right side of the equal sign by adding it to both sides of the equal sign: $\"8x+=+24\"$ .\r
\n" ); document.write( "\n" ); document.write( "3. Solve for x. In this equation, divide both sides by 8, which gives you x=3. \n" ); document.write( "
