The answer is C. (7,1). You can add the two equations together and the y’s will cancel out since they are opposite signs and you are left with 2x=14. Then from there you can divide both sides by 2 and get x=7. Now at this point only one option has 7 as the x-value, but if you want to solve for y you can plug 7 I or one of the equations for x, ex: 7-y=6, and you would get y=1 as your answer which fits with option C.
Answer:
12n-10=14, n=2
Step-by-step explanation:
( Twelve times of a number decreased by 10 is equal to 14 ) This sentence can be written mathematically to be: 12n-10=14
The answer: Add 10 to both sides: 12n-10=14 > 12n-10+10=14+10 > 12n=24
Divide both sides by 12: 12n=24 >
> n=2
