Answer:
Train A weighs 252 tons and Train B weighs 13 tons
Step-by-step explanation:
Let "A" represent the weight of Train A and "B" represent the weight of train B.
We can use this to set up a system of equations:
A+B=265
A-B=239
We can solve using elimination. Let's subtract the second equation from the first to cancel out A.
2B=26
Divide both sides by 2
B=13
Plug 63 back in for B in any of the two equations:
A+13=265
Subtract 13 from both sides
A=252
Train A weighs 252 tons and Train B weighs 13 tons

Answer:
p=25
Step-by-step explanation:
-5[-9=- -4] Get rid of the fraction by multiplying the whole equation by -5.
45=p+20 Then, subtract 20 from both sides.
25=p
