Is the point (2,1) a solution to the following system? 3x-2y=6. x+y=2

Answer:
No
Step-by-step explanation:
Hi,
I believe this is the explanation to the answer.
First of all, we must understand what is meant by a "solution" to a "system." A solution to a system means whatever solutions you get for x and y should be able to satisfy both of the equations in the system.
In here, we have the point (2,1). To test whether it satisfies the two equations in the system, simply plug in the values!
3(2) - 2(1) = 6 - 2 = 4
As you can see, 4 6. Let's look at the other equation.
(2) + (1) = 3
Again, as you can see, 3 2.
Hence, this point (2,1) does not satisfy the two equations, so it's definitely not a solution.

The correct answer is: " " .
__________________________________________
Note: Let's assume that this given decimal value is really:
"0.66666666666666666....." ;
(non-terminating; but repeating the singing digit, "7" ; yet rounded to:
" 0.66666667 " ;
then: " 0.666... " = ;
= (666 ÷ 111) / (999 ÷ 111) ;
= 6/9 ;
= (6÷3)/(9÷3) ;
= 2/3 ;
= " "
→ which is our answer.
____________________________________________
Or: " 0.6666... " = 666 ÷ 999 = ? ;
using calculator :
= 0.66666667 ;
→ which is the "rounded off" number of "0.6666..." ;
— (infinitely repeating) ;
→ So 666 ÷ 999 =
→ " " ;
= " " ;
→ Either use a "fraction calculator" ;
or simplify as aforementioned.
