1.3a = 3(4, -7) = (12, -21)
3a + в = (12, -21) + (-3, 6) = (9, -15)

6в = 6(-3, 6) = (-18, 36)
4a + 6в = (16, -28) + (-18, 36) = (-2, 8)
3.4a = 4(4, -7) = (16, -28)
в - 4a = (-3, 6) - (16, -28) = (-19, 34)
4.5a = 5(4, -7) = (20, -35)
3в = 3(-3, 6) = (-9, 18)
3в - 5a = (-9, 18) - (20, -35) = (-29, 53)
