<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
-47 = x + 15
Rearrange it to isolate x:
-47 - 15 = x
-62 = x

Let's Solve :
Therefore, the correct answer is 12
