Multiply the second equation by 3, so 4x-y=6 becomes 12x-3y=18.
x + 3y = -5
+ (12x-3y = 18)
______________
13x = 13
So x = 1
Plug x = 1 into any of these, such as 1 + 3y = -5, which becomes 3y = -6, and then y = -2.
x = 1
y = -2
Answer:
The answer is option A
Step-by-step explanation:
From the question given, the limit is between 5 and 7, the differentiation starts from the beginning of the trail
Answer:
5/6
Step-by-step explanation:
The sides numbered 1,2,5 are green and 2,4,6 are even
We cannot count the 2 twice, so there are 5 unique possibilities of getting either a green or an even
There are 6 total possibilities when rolling the die 1,2,3,4,5,6
P (green or even) = green or even/ total
= 5/6
The answer is 1. One solution; x=1
