Question 323083
Two angles form a linear pair. 
x + y = 180
---------------------
The measure of one angle is seven less than twice the measure of the other angle. 
x = 2y-7
---------------------

what are the measures of both the angles?
---
Substitute for "x" and solve for "y":
2y-7 + y = 180
3y = 187
y = 62 1/3
-------------
Since x+y = 180, x = 180-62 1/3 = 117 2/3
