<em>Note: I am assuming your second equation is:</em>
<em>x = 2y - 1</em>

Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
2x+y=3
x = 2y - 1
solving the system of equations using the elimination method
Arrange equation variables for elimination
Multiply x-2y=-1 by2: 2x-4y=-2
subtracting the equations
now solve -5y = -5 for y
Divide both sides by -5
Simplify
For 2x+y=3 plug in y=1
subtract 1 from both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
2(15k^2+19k+6)
I don't know if this is correct
That's a question about exponentiation.
Answer:
Kenji is wrong because he does not aply the porperty correctly.
Step-by-step explanation:
A exponetiation has this form:
<em>a </em>is the base
<em>b</em> is the power or exponent
To understand that situation it's important to know a property about exponentiation. When we have a multiplication with the same exponent and diferent bases, the result is the multiplication of the bases with the same exponent. Let's see this above, in mathematical language:
Examples:
Now, we can say why Kenji is wrong. It's easy simplify ! We know that the result is , but Kenji multiplied the bases and added the exponents, that's why he is wrong.
I hope I've helped. ^^
Enjoy your studies! \o/
