Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:
That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,

Answer:
10 days
Step-by-step explanation:
10 workers work 2 hrs a day for 5 days, so the work content is 10*5*2=100 manhours.
2 people work 5 hrs a day, so they deliver 10 manhours a day. To finish a work of 100 manhours,they’ll need 100/10=10 days.
The answer is 10 days.
I say, just take a minute and remember why you are doing it. If you love it, just remember the love that you get from it. If you don't love it, then just think of it as getting experience for something else in life.
I get nervous before my cross country/track/half marathon races and all I think about is why I'm doing it in the first place.
Hope it helps!
The amount of different combos possible would be 165 // Hope this helped, comment below for any clarifications // Brainliest ;) Thanks!! //
It is -12, negative + negative is Negative unless if its with a positive it will cancel out
ex, -12 + 6= -6
