Deanna Montes · Answer 1

Set up a system of equations:

sum of 3 #s is 125:

x + y + z = 125

first # is 5 more than third:

x = z + 5

second # is 3 times the third:

y = 3z

then use that info to solve for the numbers

Nicholas Delacruz · Answer 2

(x) + (5+x) + (3x) = 125

5x=120

x=24

The third number is 24

The first number is 29

The second number is 72
