Answer

Problem

Simplify the expression
(-2xy + 5xy - (-3xy) - (-10xy) + (-36xy))

Formula:

By using basic operations

(-) * (-) = ( + )

Formula:

By using basic operations

( + ) * (-) = (-)

Step

After simplification we get

(-2xy + 5xy + 3xy + 10xy - 36xy)

Hint

xy as common

Step

Take xy as common

( - 2 + 5 + 3 + 10 - 36 )xy

Hint

Add the numbers

Step

After adding we get

-20 xy
