The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45

The numbers are 18 and 72

Represent the numbers with x and y.

So, we have the following equations

x = 18 + 3y

x - y = 54

Substitute x = 18 + 3y in the second equation

18 + 3y - y = 54

This gives

18 + 2y = 54

Subtract 18 from both sides

2y = 36

Divide both sides by 2

y = 18

Recall that:

x = 18 + 3y

So, we have:

x = 18 + 3*18

x = 72

Hence, the numbers are 18 and 72
