In the problem, how do you get 6,300,000 using the digits 1-7 to create a
seven-digit number that can be rounded to 6,300,000.
We can use the numbers according to the rule of rounding values, 0-4 and
5-9.
Hence the numbers are:
1. 6, 290,000 = 6, 300, 000
2. 6, 310, 000 = 6, 300, 000
Therefore the numbers concerned in the given value is in the place order of
ten thousand which will determine the hundred thousands’ value.
A, C, D, F? Not sure but took a good guess
Substitute the value of x in equation 2. Then you'll get y=3. Then again substitute the value of y in x=1+y, you'll get x=4
