Answer:
{-3, 5}.
Step-by-step explanation:
y = x + 8
x + y = 2
Substitute y = x + 8 in the second equation:
x + x + 8 = 2
2x + 8 = 2
2x = -6
x = -3
Now plug this into the first equation
y = -3 + 8 = 5.
Well, 3 * 7 is 21. So 3,000 * 70 is 210,000. This is because of the zeros after 3 and 7, obviously, but more importantly, if it were only 3,000 * 7, your answer would be 210,000.
