Answer:

(2, 0)

There is one solution

Step-by-step explanation:

Given the set of equations

x+y = 2

2x+y = 4

Substract both equations

x - 2x = 2 - 4

-x = -2

Multiply thrugh by -1

-1(-x) = -1(-2)

x = 2

Substitute x = 2 into equation1 ;

From 1, x+y = 2

2 + y = 2

y = 2-2

y = 0

hence the solution to the system of equation is (2, 0). Hence there is only one solution
