Answer:

x = 26 and y = 17

Step-by-step explanation:

x is the larger number and y is the smaller number

the difference is 9 ⇒ x - y = 9

Five times the smaller is 7 more than 3 times the larger ⇒ 5y - 3x = 7

x - y = 9 ⇒ x = 9 + y (1)

substitute x = 9 + y in  5y - 3x = 7

5y - 3(9 + y) = 7

5y - 27 - 3y = 7

2y = 7 + 27

2y = 34

y = 34/2

y = 17

x = 9 + 17

x = 26
