Assume x tp be the number of red lentils and y to be the number of yellow lentils Kiran bought.

1.The system of equations will be

x+ y = 2.5 and

1.8 x + 1.8 y = 4.05

2.Elena can say this because when we multiply both sides of

x+y = 2.5 by 1.8, we have 1.8 x + 1.8 y = 4.5.This cannot be correct because we already have an equation saying 1.8 x + 1.8 y = 4.05. Solving both equations gives us no solution.

3.The system of equations will be x + y = 2.25 and

1.8 x + 1.8 y = 4.05

4 No, because x + y = 2.25 and 1.8 x + 1.8 y = 4.05 are equivalent equations, so they share the same solution. There are many pairs of values that meet both the weight and price constraints.
