Question

a and b forms a linear pair.if a-b=80 find the values of a and b

Answer 1

Answer:

b=0; a=80

Step-by-step explanation:

a=80-b---->(i)

a-b=80----->(ii)

now substituting the value of  a from equation (i) in equation (ii)

or, a-b=80

or, (80-b)-b=80

or, 80-b-b=80

or, 80-2b=80

or, 80-80=2b

or, 0/2=b

or,b=0#

again,

or, a=80-b

or, a=80-0

or, a=80#

or,
