The recent institution question and answer asked over students to express what they assume is the main important aspect for a student to do in order for you to hit success. Of many responses, one which that stood out was practice. Successful persons generally are not born successful; they become successful by hard work and commitment. This is how you can reach your goals. followed below are one of the answer and question example that you could simply implement to practice and enhance your knowledge and also give you insights that should guide you to keep up your study in school.

## Question:

Write A real world problem that can be solved by the equation y + 8 = 20.Then solve your problem.

If a real world problem assumption of having pen to Kelly and Allen then  Kelly have 8 pens and Allen purchase 12 pens.

Linear Equation:

A linear equation is an algebraic equation that have some constants and some variables formed in degree one of variable form.

Kelly and Allen purchasing some pens together and if Allen purchase some pen but Kelly purchase 8 more than Allen. Also the total purchasing is 20 then we have to find number of pens for each one.

According to the condition we have linear equation

How to find solution of linear equation in one variable?

Number of pens purchased by Allen +  Number of pens purchased by Kelly = 20

y + 8 = 20

Subtract 8 from both the sides we have

y = 12

Therefore Allen purchase 12 and Kelly purchase 8 pens.
