X is steve's age
3X is his father's age
37 is his mother's age.
Since the sum is 89, we can create an equation to add them all up:
x + 3x + 37 = 89
x + 3x is 4x, so now we have
4x + 37 = 89
Now we can subtract 37 from both sides of the equation, so we are left with:
4x = 52
Now we can divide both sides by 4, so we get
x = 13
Now we know Steve is 13.
To figure out his dad's age, we need to do 13 x 3
Now we know Steve's dad is 39.
