Answer:

x =68 and y = 17

Step-by-step explanation:

If we called the larger number is x and the smaller number is y, we are given that:

x = 4y (1)

x + y = 85 (2)

If we put (1) into (2), we got:

4y + y = 85

5y = 85

5y / 5 = 85 / 5

y = 17

Because y = 17 and x = 4y so we gotL

x = 17 * 4

x = 68

Hope this helped :3
