Menjawab:
# (x, y) = (3,5) #
Penjelasan:
Jika #color (white) ("XXX") y = 1 / 3x + 4 #
dan #color (white) ("XX") y = 2x-1 #
kemudian
#color (white) ("XXX") 2x-1 = 1 / 3x + 4 #
#color (white) ("XXX") 5 / 3x = 5 #
#color (white) ("XXX") x = 1 #
#color (white) ("XXXXXXX") #dan mengganti ini #rarr y = 1 / 3x + 4 #
#color (white) ("XXXXXXXXXXXXXXXXXXXX") # memberi # y = 5 #
