The pair of linear equations has a unique solution. Then the pair of equations is consistent and independent.
<h3>What is the linear system?</h3>It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
are the linear equations.
We know the condition,
The pair of equations satisfies the condition.
The pair of linear equations has a unique solution.
If a system has at least one solution, the system is consistent.
If the consistent system has exactly one solution then the system is independent.
Thus, the pair of equations is consistent and independent.

Answer:
About 17 weeks
Step-by-step explanation:
Given
Ryan:
<em /><em> (weekly)</em>
Sarah:
(weekly)
Required
Determine the number of weeks they have the same cards
Represent the number of weeks with w:
For Both individuals, number of card at any given week is:
So,
For Ryan, the expression is:
For Sarah, the expression is:
To determine the number of weeks, we have to equate both equations:
Collect Like Terms
Solve for w
16.6 implies about 17 weeks, because 16.6 approximates to 17
<em>Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks</em>
