Answer:
3. The first equation can be multiplied by 3 and the second equation by 2.
Step-by-step explanation:
2 x + 3 y = 25 (1)
-3 x + 4 y = 22 (2)
Multiply equation (1) by 3 and (2) by 2.
3(2x) = 6x
2(-3x) = -6x
When you add the two equations, x will get cancelled last

Answer:
(4)
Step-by-step explanation:
L'intersezione si occupa di elementi comuni
segno per intersezione = ∩
A = (1,2,3,4,5)
B = (3,4,5,6,7)
C = (2,4,6,8)
(A∩B)∩C
(A∩B) = (3, 4, 5)
(A∩B)∩C = (4)
