CBSE Class 10 Maths Graphical method of solution of a pair of linear equation

Assume number of multiple type questions be x and number of short answer type question be y.Set up the linear equation according to given conditions.As the total number of questions is 75,So first equation comes out to be x+y=75. And next equation can be set up by using the given conditions.
Recall linear equations in two variables
Apply the condition for infinitely many solutions.
Recall linear equations in two variables.
Put the value of y in the given equation.
Compare the ratios of coefficients of x, y and constant term.
Let the no. of â‚¹1 coins and â‚¹2 coins be x and y.
Then the pair of linear equations are: \\(x+y=50\\) and \\(x+2y=75\\) solving both we get 25, â‚¹1 coins and 25, â‚¹2 coins
