Y = 25x + 35
y = 5x + 45
Thus,
25x + 35 = 5x + 45
25x - 5x = 45 - 35
20x = 10
x = 10/20 = 1/2
y = 5x + 45
y = 2.5 + 45
y = 47.5
Thus, x = 1/2, y = 47.5
This is the answer Hope it helps :)
6 Points is my guess, there is a 50, 50 chance that he will get it, 50% of 4 is 2, two times 5 is 10, - (2*2) 4= 6 points
