Answer:
x = 20 y= 12
Step-by-step explanation:
x+y=32
x−y=8
Add the two equations together to eliminate y
x+y=32
x−y=8
----------------
2x = 40
Divide each side by 2
2x/2 = 40/2
x = 20
We know x so we can find y
x+y = 32
20+y = 32
20+y-20 = 32-20
y= 12

Answer:
Second barn: 912 bricks
Third barn: 1826 bricks
Fourth barn: 1402 bricks
Step-by-step explanation:
(English question: The barn consists of 1259 bricks. The second barn has 347 bricks less. The third has 567 bricks more than the first barn and the fourth barn has 490 bricks more than the second barn. How many bricks consists of the second, third and fourth barn.)
If the second barn has 347 bricks less than the first barn, so the second barn has:
1259 - 347 = 912 bricks
The third barn has 567 bricks more than the first barn, so the third barn has:
1259 + 567 = 1826 bricks
The fourth barn has 490 bricks more than the second barn, so the fourth barn has:
912 + 490 = 1402 bricks
