Answer:
Step-by-step explanation:
9514 1404 393
Answer:
- A + B = 389
- A - B = 263
- A = 326 tons
- B = 63 tons
Step-by-step explanation:
The first equation is an expression of the first given relationship:
A + B = 389 . . . . . . where A and B represents trains weights, respectively
The second equation is an expression of the relationship described in the next two sentences:
A - B = 263
__
These equations can be solved by adding them together:
(A +B) +(A -B) = 389 +263
2A = 652 . . . . . . simplify
A = 326 . . . . . . . .divide by 2*
B = 326 -263 = 63
Train A weighs 326 tons.
Train B weighs 63 tons.
