An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign
x + y = 110
y - (1/2)x = 20
The number of marblesonechildren had is 50.
The number of marblesotherchildren had is 60.
What is an equation?
An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign.
Example:
2x + 4y = 6 is an equation.
2x + 4 is an equation.
We have,
Totalnumber of marbles = 110
Number of children = 2
Number of marblesonechildren has initially = x
Number of marblesotherchildren has initially = y
Now,
x + y = 110 _____(1)
After one child had losthalf her marbles and the otherlost 20 they had an equalnumber.
This means,
x - (1/2)x = y - 20
(1/2)x = y - 20
y - (1/2)x = 20 _____(2)
From (1) and (2) we get,
x = 110 - y _____(3)
Putting (3) in (2)
y - (1/2)x = 20
y - (1/2)(110 - y) = 20
y - 55 + (1/2)y = 20
(3/2)y = 20 + 55
(3/2)y = 75
y = (75 x 2) / 3
y = 25 x 2
y = 50
Now,
Putting y = 50 in (3) we get,
x = 110 - y
x = 110 - 50
x = 60
Thus,
The number of marblesonechildren had is 50.
The number of marblesotherchildren had is 60.

The answer is 9,000 or 9 thousand.
Further explanation
9 ten thousand are a unit form. The standard form is 90,000.
Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.
The key problem is working out the value of 90,000 divide by 10. This is a division operation.
Option-1
Both numbers are divided by 10.
The result is
Option-2
Division operations can be written as fractions, like this.
The numerator and denominator are both divided by 10, or 'cross out a zero from both'.
The result is
- - - - - - -
If x is divided by y equals z, then x is equal to y multiplied by z.
Let's prove it!
This is proven.

adult boa = 9 * 18 + 2 = 164 inches
Since all the information is given, then merely put the necessary facts in order.
Had the length of the newborn been unknown, it would have been represented by x.
9x + 2 = 164
9x = 164 - 2
9x = 162
9x/9 = 162/9
x = 18
Next add 162 + 2 = 164
Last put 164 on the papper
