Answer:
A ) subtract the second equation from the first equation
Step-by-step explanation:
2x + 3y = 7
2x - 4y = -5
subtracting the second equation from the first equation we get,
7y = 12
y=12/7
This is the correct option
Answer:
The product would be -27x.
Step-by-step explanation:
First you use the distributive property to distribute the -9x to the 5 and the -2x. Then you would get -45x+18x. 18x because when you multiply a negative and a negative you get a positive. Then, you add those two and you should get -27x.
