Question

Subtract 6xy from -12xy
subtract (a-b) - (a+b)

Answer 1

-12xy-6xy (-a-b=-(a+b))

-18

(a-b)-(a+b) open bracket

a-b-a-b a will be cut by -a

Answer 2

Given:

$a)\ -12xy-6xy\\b)\ (a-b) - (a+b)$

We have to solve the above expression.

As we know that adding two or more numbers together is known as an addition.

Addition as denoted by(+).

We are solving in the following way:

We have,

$a)\ -12xy-6xy\\b)\ (a-b) - (a+b)$

Solving the above equation further we get,

$a)\ -12xy-6xy\\\\=>-18xy$

and

$b)\ (a-b) - (a+b)\\\\=>a-b-a-b\\=>-2b$

Hence, the solution of the above equation is

$a)\ -18xy\\b)\ -2b$
