the cost of a ball pen is Rs.5 less than half of the cost of fountain pen. write this statement as a linear equations in two variables.
Answers
Step-by-step explanation:
y=x/2 -5 or x-2y-10=0 , where x is the cost of one fountain pen and why is that of one ball pen
Let's represent the cost of a fountain pen as "x". Then, the cost of a ball pen can be represented as "x/2 - 5".
This can be translated into a linear equation:
y = x/2 - 5,
Where y represents the cost of a ball pen and x represents the cost of a fountain pen.
In this equation, x/2 represents half of the cost of a fountain pen, and the subtraction of 5 represents the fact that the cost of a ball pen is Rs.5 less than half of the cost of a fountain pen.
This equation shows the relationship between the cost of a ball pen and a fountain pen and can be used to find the cost of one item given the cost of the other. For example, if we know that a fountain pen costs Rs.20, we can substitute this value into the equation to find the cost of a ball pen:
y = 20/2 - 5
y = 10 - 5
y = 5
So, if a fountain pen costs Rs.20, then a ball pen costs Rs.5.
