Answer:
5x-y=7
2x+y=0
Step-by-step explanation:
Given system of equations:
5x-y=7 ------------- eq1
2x+y=0 ------------ eq2
By adding both equations we get:
7x = 7
Dividing both sides by 7 we get:
x = 1
Now putting value of x in eq2
2(1) + y = 0
2+ y = 0
y = -2
So the solution set is (1 , -2)
By looking at the given graph:
The intersection point of two lines is (1 , -2)
Hence proved that the given system of equations matches the graph.
