ANSWER

Yes it is very true


Step-by-step explanation

If the two equations intersect at
(50,60) then this point must satisfy the two equations.



3x+2y=270---(1)

We substitute
(50,60) in to erquation (1)



3(50)+2(60)=270



150+120=270


270=270





y=(4)/(5)x+20 ---(2)


We now substitute
(50,60) in to erquation (2) also



60=(4)/(5)(50)+20



60=40+20



60=60


Since the point satisfy all the two equations, it is true that they intersect at
(60,50)
