Answer:
The correct answer is B.
Step-by-step explanation:
Multiply the first equation by -7, and the second equation by 8, and then add.
What you're trying to do is cancel them out so they have to opposite signs in order for them to cancel out. You can't do that if the signs are the same, which is what option A suggests doing. B is the correct answer.
If it is asking about what is 136x3 then that would be 816
You just find the numbers that you can multiply to get -28
Answer:
-1, +3
Step-by-step explanation:
The equation can be factored as ...
2(x² -2x -3) = 0
2(x -3)(x +1) = 0
The zeros are the values of x that make the factors zero:
x = 3, x = -1
The zeros are -1 and 3.
