8 years after

Step-by-step explanation:

Let's make the equation x

B will be 4 times older after x years

We can list the equation like this:

4(11+x)=68+x

We can simplify the left side

44+4x=68+x

We will need to subtract x on both side to move the x to one side.

we will get 44+3x=68

Then we can subtract 44 on both sides to make the number move to 1 side we will get 3x=24

And we can divide by 3 on both sides.

x=8

That's the answer~

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
