Answer:

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~

xew

In x amount of years, B will only be A x 4

For A that would be 4 (11 + x), for B that would just be 68 + x

4(11 + x) = 68 + x

44 + 4x = 68 + x

44 + 3x = 68

(3 x 8) = 24, 44 + 24 = 68

So 8 must be the answer

in 8 years, B will only be 4 times as old as A

Hope This helps!
