Question

subtract (2x-7y+4z) from the sum of (2x+4y-4z) and (-2x+3y-2)​ please answere a little fast​

Answer 1

Answer: The equation is $-2x+14y-10z$

Step-by-step explanation:

Given: equations $2x-7y+4z$   --------$(1)$

                            $2x+4y-4z$    --------$(2)$

                  and $-2x+3y-2$      --------$(3)$

To find: the final equation after subtraction of the first equation from the sum of the next two equations.

Solution: First, we'll find the sum of the two equations i.e.,

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

we get, $0x+7y-6z$   ---------$(4)$

Now subtracting equation $(1)$ from the equation $(4)$ ,

$(0x+7y-6z)-(2x-7y+4z)$

we get, $-2x+14y-10z$
