7x + -2x = 10

Combine like terms: 7x + -2x = 5x

5x = 10

Solving

5x = 10

Respected Madam,

Subject :- Application for one day leave

I humbly request that I am a student of class X of your school. On returning home from school yesterday, my bicycle collided with a scooter, resulting in an injury to my hand. According to the doctor, it will definitely take at least 1 day to heal. Therefore, I will not be able to attend school one day. I request you to grant me leave on 4 December. The doctor's certificate is attached to the application.

Thank you

Yours obediently
