The cost ofof two pizza and one burger is rupees 450.This situation as a linear equation in two variable and also draw a graph.
Let the cost of the 2 pizzas be Rs ' 2x ' and the cost of 1 burger Rs ' y '.
So, according to the given conditions,
2x + y = 450.
You can plot the graph according to the following:
If x = 0, y = 450. So, (0, 450) is a solution of the equation.
If y=0, 2x = 450, which gives x = 225. So (225,0) is one of its solutions.
By joining these two points, we get the graph.
