Question

subtract 3x-2y+9 y from 4x+y-z​

Answer 1

Answer:

4x+ y - z - (3x-2y+9z)

=4x+y-z-3x+2y-9z

=x3+y-10z

Answer 2

Answer:

∴ On subtraction of $3x-2y+9$ from $4x+y-z$, we get $x+3y-z-9$.

Step-by-step explanation:

In context with question asked,

• We have to subtract $3x-2y+9$ from $4x+y-z$.
• Subtraction is one of the important arithmetic operation of mathematics among division, multiplication, addition and subtraction.
• With the help of subtraction, we can find the difference between the given quantities or expressions.
• In subtraction, -ve*-ve=+ve and -ve*+ve=-ve.
• Now, the given expression is,

       $4x+y-z-(3x-2y+9)=4x+y-z-3x+2y-9$

                                         = $x+3y-z-9$    

• ∴ On subtraction of $3x-2y+9$ from $4x+y-z$, we get $x+3y-z-9$.
