In your own words explain the place value relationship when the same two digits are next to each other in a multi digit number

In a place value relationships. The relationship between 2 the same digit place next to each other is the value of the number to left is 10 times bigger than to the value to the left and from the decimal point to the right is 10 times smaller of value than the digit in their right.

Let say for example:
1111
1 thousands, 1 hundreds, 1 tens, and 1 ones.
Let’s start from 1 = 1 x 10 = 10
That would be 10 X 10 = 100
then 100 X 10 = 1000

Notice that their value increase base on its place value if we multiply the given number by 10. 

Another one is

912.98 in where 9 is hundreds, 1 is tens, 2 is ones and after the decimal points, in where  9 is tenths and 8 is hundredths.

Notice each place value next to each other. Each value is ten times in difference.

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
