Answer:
<h2>
46</h2>
Step-by-step explanation:
x - age of a son three years ago
3x - age of a father three years ago
x + 3 - age of the son now
3x + 3 - age of the father now
x + 3 + 5 - age of the son in five years time
3x + 3 + 5 - age of the father in five years time
in five years time, the father will be twice as old as his son, so:
3x + 3 + 5 = 2(x + 3 + 5)
3x + 8 = 2x + 16
3x - 2x = 16 - 8
x = 8
x + 3 + 4 - age of the son in four years time
8 + 3 + 4 = 15
3x + 3 + 4 - age of the father in four years time
3×8 + 3 + 4 = 31
the sum of their ages in four years time:
15 + 31 = 46

Step-by-step explanation:
Hi!!
Okay, so here is the equation needed to solve:
85.00 = 25.00 + 12.00x
Subtract 25 from both sides
85 -25 = 25 - 25 + 12x
Then, you get:
55 = 12x
Divide 55 by 12
55/12 =x
so x = 6
Hope this helps!
