A:
Answer:8 years afterStep-by-step explanation:Let's make the equation xB will be 4 times older after x yearsWe can list the equation like this:4(11+x)=68+xWe can simplify the left side44+4x=68+xWe will need to subtract x on both side to move the x to one side.we will get 44+3x=68Then we can subtract 44 on both sides to make the number move to 1 side we will get 3x=24And we can divide by 3 on both sides.x=8That's the answer~
