Question is in here (highlighted)
If possible any other questions can be answered too.
Please show working so i can understand.
Thanks :)
OK, you have two equations.
A. Liddell is x and Lewis Carroll is y.
When you add the ages of x+y, you get 46.
x+y=46
You also know that Lewis Carroll is 20 years older than Alice. So x+20 is Lewis' age.
Now, rewriting the x+y equation with the new information.
x+(x+20)=46 and solving for x
2x+20=46
2x=26
x=13
