Answer:
train A = 374
train B = 95
Explanation:
First, set up an equation that will help you: (x + 279) + x = 469
train A = x + 279
train B = x
To begin, subtract 279 from both sides of the equation: 2x = 190
Then divide both sides by 2: x = 95
Now plug 95 in for x on the original equation: 95 + 279 + 95 = 469
Since that is true, we have done the problem correctly.
Now plug 95 in for both the equations for train A and B:
train A = 95 + 279 = 374
train B = 95
I hope this helps!
