fungsi y = 2x + 1 dan y+ 3x - 3 / 2x - 1 carilah titik potongnya Tolong ya beserta caranya :-)

y = 2x + 1
y = (3x -3)/(2x - 1)

y = y
2x + 1 = (3x -2)/(2x -1)
(2x +1)(2x - 1) =  3x - 2
4x² - 1 = 3x - 1
4x² - 3x = 0
x ( 4x - 3)= 0
x= 0 atau 4x - 3=0 
x = 0 atau x = 3/4

y = 2x+ 1
x= 0 , y = 2(0) + 1 = 1 --> A(x,y) = (0,1)
x = 3/4 , y = 2(3/4) + 1 --> B(x,y)= (3/4, 5/2)
