1 2/3 cups of sugar should be used with 5 cups of flour.
Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:

To solve the system, first we multiply by 2 both sides of the second equation, and we get:

So now the system is

Now we add the two equations, and we get:

So, we get

Now we can substitute this value of y into the eq.(2), and we get:

-4u=16
U=16÷(-4)
U= -4 To check -4(-4)=16
16=16
