Answer:
Question 1) Given,
a and b form a linear pair.
So, a + b = 180
a = 180 - b (eq.1)
Also given,
(3a - b) = 80 (eq.2)
putting Eq.i in Eq. ii,
3 (180 - b) - b = 80
540 - 3b - b = 80
540 - 4b = 80
540 - 80 = 4b
b = 460/4 = 115
Now, putting value of b in Eq. 1,
a + b = 180
a = 180 - b = 180 - 115 = 65
Therefore,
a = 65 and b = 115

Answer:
Q1 a=65, b=115
Step-by-step explanation:
a+b=180(linear pair)
let it take it as equation 1
3a-b=80
let it take it as equation 2
