Answer:
2x-6 I think
Step-by-step explanation:
Subtract the 2 equations
7x+2y=-19
- -x+2y = 21
--------------------------
8x +0y=-2
x= -1/4
That's true. If the integers both have the same sign, then their product and quotient are both positive. If signs are different, then product and quotient are both negative.
The answer is 0.003021148
