No, because if you start reading first and you both go at the same rate, you'll end up finishing the book first.

y= the number of pages completed

x= number of days

My situation:

y=10x+20y=10x+20

My friend's situation:

y=10xy=10x

For any value of x, y will always be greater in my situation than in my friend's situation.

Hence, I will finish the book before my friend.

In simple words, if I start reading first and we both go at the same rate, I'll end up finishing the book first.

What represents a system of linear equations?

A system of linear equations can be represented in matrix form using a coefficient matrix, a variable matrix, and a constant matrix. Consider the system, 2x+3y=85x−y=−2. The coefficient matrix can be formed by aligning the coefficients of the variables of each equation in a row.
