Let the Price of 1 magzine = x
Margin on 1 Magzine = (10%)(x) rupees = 0.1 x
Margin on 42 Magzines = 42(0.1 x) = 4.2 x
Also
Let the Price of 1 books = y
Margin on 1 Book = (15%)(y) rupees = 0.15 y
Margin on 14 Books = 14(0.15 x) = 2.1 y
Basic Pay of Adam = 200
Amount that Adam earned last week = 200 + 4.2 x + 2.1 y

The sum of angles in a triangle is 180, so you add up the angles and set it equal to 180.
6c+5c+37=180
11c+37=180
11c=143
c=13
Then if you need the values of the angles, just substitute 13 for c.

Answer:
3x - y = -1
Step-by-step explanation:
Standard form of equation is Ax + By = C
y - y1 = m (x -x1)
y - 7 = 3 (x - 2)
y - 7 = 3x - 6
3x - y = -7 +6
3x - y = -1
