The integers are x - 1, x and x + 1
x - 1 + x + x + 1 = 186
3x = 186
x = 186/3 = 62
Therefore, the numbers are 61, 62 and 63
Answer:
This system has one solution (x=2 and y=2), then the answer is A.
Step-by-step explanation:
The system of equations is:
(1)
(2)
Let's multiply the first equation by 2 and subtract it to the second equation


Using this value in (1) we can find y.


Therefore, this system has one solution (x=2 and y=2), the answer is A.
I hope it helps you!
Answer:
Q=(0.4.-1.7)
R=(2.4. 9.3)
S=(-10.6. 7.3)
Step-by-step explanation:
Just did it and got it wrong and these are the correct answers
Step-by-step explanation:
2 + x + 2x = 14
3x + 2 = 14 (combine like terms)
3x = 12 (subtract 2 from both sides)
Hence the answer is 3x = 12. (B)
