Question

Answer 1

First, you need to set up a system of equations, where movie A is represented as (a) and movie B is represented as (b).

 

So...

a + b = $1143 million

a = b - $139 million

 

Then, you just plug the second equation into the first one and solve for b, and when you find b, you plug that value back in to find the value for Movie A.
