Question

Simplify- [5-3x+2y-(2x-y)]-(3x-7y+9)​

Answer 1

[5-3x+2y-(2x-y)]-(3x-7y+9)

=[5-3x+2y-2x+y]-(3x-7y+9)

=[5-5x+3y]-3x+7y-9

=5-5x+3y-3x+7y-9

=10y-8x-4

Answer 2

Answer:

(10y - 8x - 4)

Step-by-step explanation:

In the given question,

We have been provided that,

[5-3x+2y - (2x -y)] - (3x-7y+9)

So on solving and opening up the brackets from the equation using BODMAS rule we get,

(5 - 3x + 2y -2x + y) - (3x - 7y + 9) = (5 - 5x + 3y) - 3x + 7y - 9

On simplifying it further we get,

(5 - 5x + 3y) - 3x + 7y - 9 = 10y - 8x - 4

Therefore the final simplified equation is given by,  (10y - 8x - 4).
