Question

Substituting y=-2 in the equation Solve the problem -2x+_____=-12

Answer 1

If b=-2 then -2x+-2 =-12 making x equal 5 ,5 times -2 equals -10 plus negative 2 equals -12

Answer 2

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.
