Question

A number is twelve less than five times the measure of a number and they form a linear pair

Answer 1

Step-by-step explanation:

Let the number be x and other number be y .

According to question ,

x= 5y-12 (eq.1)

Also , x+y = 180 (Linear pair ) (eq.2)

Substituting the value of x = 5y-12 in eq.2 , we get-

5y-12+y =180

6y= 180+12

6y= 192

y=32

Putting y = 32 in eq.1 , we get -

x=5×32 -(12)

x=148
