Solve the system of equations by multiplying and adding. braceleftze −6x + 9y = −39 8x + y = 0 Write the solution as an ordered pair: . If necessary, write the answer in fraction form.

Step-by-step explanation:

the system of equations is:

First, we multiply the second equation by -9:

and now we add this to the first original equation:

we have eliminated the y variable, so we can solve for x:

with this value of x, we substitute it on the second of the original set of equations to find the value of y:

the answer as an ordered pair is:
