Question

half a no. incresed by 10 is 12 .find the no.​

Answer 1

Answer:

The half of a number is increased by 10 is 12. What is the number?

Flexible support where it's needed.

Remember that “of” means multiplication, so from your question we infer the following equation:

(1/2)x + 10 = 12

First, subtract 10 from both sides:

(1/2)x = 2

Multiply both sides by 2 to eliminate the fraction:

x = 4

Now substitute for x in the original equation to prove this:

(1/2)x + 10 = 12

x = 4

(1/2)4 + 10 = 12

4/2 + 10 = 12

2 + 10 = 12

12 = 12
