simplify (x+y)-(x-y)

Solution

simplify

(x + y) - (x - y)

Solution

2 y

Solution steps

(x + y) - (x - y)

Apply rule:

(a) = a

(x + y) = x + y

= x + y - (x - y)

Apply the distributive law:

- (a - b) = - a + b

- (x - y) = - x + y

= x + y - x + y

Group like terms

= x - x + y + y

Add similar elements:

x - x = 0

= y + y

Add similar elements:

y + y = 2 y

= 2 y
