Answer:
-15
Step-by-step explanation:
-3+-2*5-2=-15
You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.
Answer: c. Multiply the second equation by 2.
-2 is the answer when i figured out the problem

Answer is -15</h3>
We read this out as "negative 15" or you could write "negative fifteen".
The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.
For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.
4x+3(2x-1) -4x 3(2x-1)= 6x-3 -4x 4x+6x-4x= 6x-3
