Question

Subtract 4x-7xy+3y+12 from 12x-9xy+5y-3

Answer 1

Given:

12x-9xy+5y-3

4x-7xy+3y+12

To find:

The difference of the given expressions

Solution:

The difference between 12x-9xy+5y-3 and 4x-7xy+3y+12 is 8x-2xy+2y-15.

We can find the difference by following the given steps-

We know that the difference between the given expressions can be obtained by subtracting like terms.

The given expressions are as follows-

12x-9xy+5y-3 and 4x-7xy+3y+12

The difference=(12x-9xy+5y-3)- (4x-7xy+3y+12)

=12x-9xy+5y-3-4x+7xy-3y-12

We will bring the like terms together to obtain the difference.

=12x-4x-9xy+7xy+5y-3y-3-12

=8x-2xy+2y-15

So, we get 8x-2xy+2y-15 on subtracting 4x-7xy+3y+12 from 12x-9xy+5y-3.

Therefore, the difference between 12x-9xy+5y-3 and 4x-7xy+3y+12 is 8x-2xy+2y-15.

Answer 2

Answer:

$8x - 2xy + 2y - 15$

Step-by-step explanation:

Given that

$4x - 7xy + 3y + 12$

$12x - 9xy + 5y - 3$

To find

Subtraction of this two terms

Solution

As here subtraction of equation has to perform for this signs of 2nd expression will be change as

$(12x - 9xy + 5y - 3) - (4x - 7xy + 3y + 12)$

$12x - 9xy + 5y - 3 - 4x +7xy - 3y - 12$

now subtraction of similar term will perform

$= 8x - 2xy + 2y - 15$

hence this is the solution.
