Linear equation are the equation which has the power of the unknown variable is 1. The Emily have total 2 number of dimes coin and total 6 number of nickels coin.
<h3>Given information-</h3>Emily has 8 coins in her purse totaling 50 cents
The only kinds of coins she has are nickels and dimes.
<h3>Nickel</h3>A nickel is a coin which has the value equal to the 5 cents.
<h3>Dimes</h3>A dimes is a coin which has the value equal to the 10 cents.
Suppose the number of nickel coin is <em>x </em>and the number of dimes coin is <em>y.</em>
As total coins are 8 . Thus,
......equation 1
As the total value of the cents is 50 and nickel is equal to the 5 cents whereas the dimes is equal to the 10 cents. Thus,
Put the value of the <em>x</em> from the equation 1 in the above equation.
Thus Emily have total 2 number of dimes coin.
Put this value of y in equation 1 we get,
Thus Emily have total 6 number of nickels coin.
Hence the Emily have total 2 number of dimes coin and total 6 number of nickels coin.

Answer:
The point of intersection of the lines is .
Thus, Ariyonne's claim is incorrect.
Step-by-step explanation:
Given equations:
1)
2)
To find the point of intersection, we need to solve the given system of equations.
In order to solve the system we will use substitution method.
We will substitute value of from first equation in the second equation and solve for
So, we have
Multiplying both sides by 2 to remove fraction.
Using distribution.
Subtracting both sides by
Adding 4 to both sides.
Dividing both sides by 7.
We can find value of by plugging in
in the first equation.
So, the point of intersection of the lines is .
Thus, Ariyonne's claim is incorrect.
