o
: Subtract the equation x + y = 180 from 2x +y =320 to eliminate y and solve for x:
2
x
+
y
=
320
−
(
x
+
Y
=
180
)
________________
x
=
140
Don't forget to subtract each element in the second line.
Alternatively, because you know that
x
+
y
=
180
, you can substitute this into the given equation of
x
+
(
x
+
y
)
=
320
to solve for x:
x
+
180
=
320
x
=
140
