Answer:
Step-by-step explanation:
hello :
1) the system is : y=5x+4
y = 2x+1
so :5x+4 =2x+1
5x-2x=1-4
3x= -3 so : x= -1 but y =2x+1 put x=-1 you have : y =-1
the solution : (x,y) =( -1, -1)
2) the system is : x + y = 4
4x -y = 1
means : y = - x+4 (line red)
y= 4x-1 (line blue)
graficly : intrsection is : (x,y) =(1 ,3 )
