Answer:

H = 3

K = 0

Explanation:

To solve the system of linear equations using elimination by multiplication, we can first multiply the first equation by 3. This gives us:

3(H+2k)=3*3=9

3H+6k=9

Now we have the same coefficient (6k) on the second variable in both equations. We can now subtract the first equation from the second equation to eliminate the second variable:

3H+6k=9

-3H-6k=-9

0H=0

This tells us that the system of equations is consistent and has infinitely many solutions. To find the specific solution, we can use either equation and substitute in a value for one of the variables. For example, we can use the first equation and substitute in H=3. This gives:

3+2k=3

2k=0

k=0

Now we can substitute this value for k back into either equation to find the value of H. For example, using the first equation:

H + 2(0) = 3

H = 3

So the solution to the system of equations is:

H = 3, k = 0
