What is the solution of the system? use elimination . -12x-y=6 17x+y=4

To clarify the systems of equations:




We already have opposite coefficients for y, so combine the two equations together:



Divide both sides by 5 to get x by itself:



Because we now know x, we can plug it into one of the equations.

We will plug this value into the first equation:





Add 24 to both sides.



Divide both sides by -1 to get y by itself.



Using elimination, x = 2 and y = -30.

The correct one is c.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
