Answer:
(10,5), (-12,-6), (-18, -9), (-8, -4), (20,10)
(-15, 5), (-18, 6), (-21,7), (33, -11), (24, -8)
Step-by-step explanation:
10/5=2, -12/-6=2, -18/-9=2, -8/-4=2, 20/10=2
-15/5= -3, -18/6= -3, -21/7= -3, 33/-11= -3, 24/-8= -3
(10,5), (-12,-6), (-18, -9), (-8, -4), (20,10)(-15, 5), (-18, 6), (-21,7), (33, -11), (24, -8)
Step-by-step explanation::10/5=2, -12/-6=2, -18/-9=2, -8/-4=2, 20/10=2-15/5= -3, -18/6= -3, -21/7= -3, 33/-11= -3, 24/-8= -3
Original number = 38
10*x + y
x = y - 5
10y + x = 2 (10x + y) + 7
10y + y - 5 = 2(10(y - 5) + y) + 7
11y - 5 = 2(10y - 50 + y ) + 7
11y - 5 = 2(11y - 50) + 7
11y - 5 = 22y - 100 + 7
11y - 5 = 22y - 93
11y + 88 = 22y
88 = 11y
y = 8
x = 8 - 5
x = 3
So the original number is 38. Does that work?
3 is 5 less than 8.
83 = 2*38 + 7
83 = 76 + 7
83 = 83. Yes it works.
