Answer:

Step-by-step explanation:
Given the expression
.
we have to find the simplest form of the expression.

=
=
=
which is the simplest form of the given expression.
X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30
x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120
