What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Initially, there were the same number of blue marbles and red marbles in a bag.

Let R be the red marble and B be the blue marble.

Then the equation will be

R = B   ...1

John took out 5 blue marbles, and then there were twice as many red marbles as blue marbles in the bag.

Then the equation will be

2(B – 5) = R    ...2

From equation 1 and 2, we have

2(R – 5) = R

2R – 10 = R

         R = 10

Thus, the number of the red marble are there in the bag will be 10.
