Answer:
(10, 21)
Step-by-step explanation:
To get the point of intersection of the lines given ( it means we need to find at what value of x will correspond to the value of y)
y = 2x+1
y = x+11
insert equation i in equation ii
2x+1=x+11
2x-x = 11-1
x = 10
y = 2x+1 = 2(10)+1 = 20+1 = 21
(x,y) = (10, 21)
