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.
Answer: See below
Explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
