<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

Alright Fabian, here's the deal.
First you need to solve the inequality for k. To do this, you have to
a) distribute the -(3k + 4)
b) collect like terms: -k - 3k
c) move the term with k to the left (optional but it's a habit)
d) divide both sides by the coefficient. Check out picture for details.
