Let senior citizen ticket x and child ticket y

According to question, equations are

4x+2y=80 

---->2x+y=40   ----1.   (taking 2 common from both sides)

       y=40-2x

------->5x+7y=145   --------2

Put value of y in 2

5x+7(40-2x)=145

5x+280-14x=145

-9x=145-280

-9x= -135

x= -135/-9 = 15

Put Value of x in y= 40-2x

y=40-2*15= 40-30 =10

Prize of senior citizen ticket is 15 and child ticket is 10
