Step-by-step explanation:

To subtract : ( $x+2y+3z$ ) from ( $5x +4y+7z$ )

Solution :

• To subtract given algebraic expression, we subtract like terms together .
• Therefore, arranging given terms in correct order, we get,

       $(5x +4y+7z) - ( x+2y+3z)$

• Removing parenthesis and changing sign of terms in second bracket , we subtract given expressions by performing arithmetic operations such as addition and subtraction .

      $(5x +4y+7z) - ( x+2y+3z)$

       $= 5x +4y+7z -x -2y -3z \\\\= 5x-x +4y -2y+7z-3z \\\\= 4x +2y +4z$
