Question

Subtract 3x + y - 2z from x- z + 2y.

please give the full solution ​

Answer 1

Answer:

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

Step-by-step explanation:

3x+ y-2z-x+z-2y

(- × - =+ )

3x-x=2x

z-2z=-z

y-2y=-y

Answer 2

Answer:

Subbtract 3x+y-2z from x-z+2y

Step-by-step explanation:  from means 2nd expression to 1st expression

                                           So,    x-z+2y

                                                -  3x-2z+y

 here minus  becomes plus and plus becomes minus only when we are doing subtraction.

                                            so     x-z+2y

                               subtract        3x-2z+y

                                   ===   -2x+z+y    this will be the answer

 THIS WILL BE THE ANSWER BECAUSE THE THE SECOND ROW EXPRESSION THEIR SYBOMLS WILL CHANGE Ex:3x is there it symbol become -3x and -2z is there it symbol become +2z and +y  is there it symbol becomes -y like this way to solve expression when it is given to subtract....       OK     ....
