Determine if the solution set for the system of equations shown is the empty set contains one point or is infinite

x+y=4

x-y=0

od

1 solution

infinite

The system has unique solution.

Step-by-step explanation:

Since the system has two unknow variables and two equations, we can resolve for one variable in the first equation and replace in the second equation.

We have the system

We resolve for x in the first equation and obtain

Now, replace in the second equation the value of x,

Now, replace the value of y in the expression of x:

Then the system has unique solution, (x,y)=(2,2)

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

hi there!
