Here is my reply to another question very similar tothis one.\r \n" ); document.write( "\n" ); document.write( "Follow the steps below and you will be able to solve for t in this case.\r \n" ); document.write( "\n" ); document.write( "To solve for a variable means to isolate the variable. \n" ); document.write( "In other words, we need to place x all alone on one side of the equation. \n" ); document.write( "-3x + 7 = 2y + 3 \n" ); document.write( "Subtract 7 from both sides. \n" ); document.write( "-3x = 2y + 3 - 7 \n" ); document.write( "-3x = 2y - 4 \n" ); document.write( "We now divide both sides by -3 to isolate x. \n" ); document.write( "x = (2y - 4)/-3 \n" ); document.write( "Did you follow? \n" ); document.write( " \n" ); document.write( " |
