<h2>Answer:</h2>
The first consecutive odd number is: 9
and the second consecutive odd number is: 11
<h2>Step-by-step explanation:</h2>Let the two consecutive odd numbers be: a and a+2
( Since, we know that the difference between two consecutive odd or two consecutive even numbers is always 2 )
Now, it is given that:
Three times the first is 5 more than twice the second.
i.e.
Hence, we get:
The first consecutive odd number is: 9
and the second consecutive odd number is: 9+2=11
Answer:
The value of a=300 and value of k=200
If you solve the above system of equations by elimination method, you will get the same values of a and k.
In Equation 1 both variables k has 1 as their coefficient.
Step-by-step explanation:
We need to solve the system of equations using substitution method
The equation are:
For substitution method, we find value of k from equation 1 and put in equation 2
Putting it in eq(2)
So, we get value of a = 300
Now finding value of k by putting value of a in equation
So, we get value of k =200
The value of a=300 and value of k=200
If you solve the above system of equations by elimination method, you will get the same values of a and k.
In Equation 1 both variables k has 1 as their coefficient.
