Answer:
x= 0 and -6
Step-by-step explanation:
you multiply the 2 equations together getting x^+ 6x -27.
you then subtract the 27 on the other side getting x^2 +6x =0. Then you would find the value that make the equation equal to 0. And the only 2 values are 0 and -6. 0 bc well everything multiplied by it is 0. and -6 bc if you square -6 you get 36 and when you multiply 6 by -6 you get a negative number therefore resulting in 0.
