Question

Subtract 2xy + 5yz from - 9yz + 4yx.​

Answer 1

Answer:

On subtracting $2xy + 5yz$ from $-9yz + 4yx$  we get , $2y ( -7z + x )$ .

Step-by-step explanation:

To subtract : $2xy + 5yz$ from $-9yz + 4yx$ .

Solution :

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

         $\left(-9yz + 4yx )-\left(2xy + 5yz)$

• Removing parenthesis by changing sign of terms in second bracket and performing arithmetic operation such as subtraction and addition we find the value of expression .  
• $\left(-9yz + 4yx )-\left(2xy + 5yz)$

         $=-9yz + 4yx -2xy -5yz\\\\= - 14yz +2xy \\\\=2 y ( -7z + x )$
