Answer: x=5
Step-by-step explanation:
Assuming that you are using the variable "y" in the space (meaning I took your equation to be -2x+y=-12), you used the value of -2. This gives you -2x-2=-12. Wait! We can add -2 to both sides, which gives us -2x=-10. We can then divide -2 from both sides, which makes x stand alone, and the other side to be 5. Therefore x=5.
Remember that I am writing this solution assuming that you are using the variable "y" in the blank space with a co-efficient of 1.
