Movie tickets for two adults and four children cost $50. An adult ticket cost eight dollars more then a child ticket find the cost of an adult ticket

Lets call adult as X and children as Y

2 (X) + 4 (Y) = $50

Adult ticket is $8 more than children

X=Y+8

Plugging the above in the first equation

2 (Y+8) + 4 (Y) = 50

2Y+16 + 4Y=50

6Y+16=50

6Y=50-16

6Y=34

Y=34/6

Y=5.67

X=5.67+8

X=13.67

Adult = $13.67
