Question

Half a number increased by 10 is 12. What is the number?​

Answer 1

Step-by-step explanation:

Let the no. be y.

1/2y + 10 = 12

1/2y = 12-10 = 2

y = 2×2=4

Answer 2

Answer:

let the number be x.

Half of the number=x/2

As per problem,

Half the number increased by 10 = 12

x/2 + 10 = 12

x+20/2= 12

x+20=12×2

x= 24-20

x=4.

Therefore the number is 4
