Two numbers have the same digit in the millions period, the same digits in the thousands period, and the same digits in the ones period. do these numbers have the same value

The place value pattern is a system of numbers in which the position of a digit in a number determines its value. Every period (every place) has value that is 10 times bigger than the value on its right. (ones, tens, hundred, thousands,..)
If two numbers have the same digit in the millions period, the same digits in the thousands period, and the same digits in the ones period it does not mean that they have the same value.
Two numbers have the same value if they have the same digits in all periods, which includes also the tens period.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
