The company lost a little less than $100.
Since the number is negative, we know that they lost money. If it was positive, it would've indicated they made money. If they made no money, they would've broken even. This narrows it down to the last two. Since 98 < 100, we know they lost less than $100, which leaves us with the last one.
So you need to do substitution. First solve the easier equation for 1 variable.
x+y=-1 now subtract x to get y=-x-1. Then plug this into the top equation to get 2x+7(-x-1)=2. Next distribute to get 2x+-7x-7=2. Now combine like terms to get -5x=9 so x=-5/9. Now you have to plug this back into the original equation to get y. 2(-5/9)+7y=2, so -10/9 +7y=2. No move terms around to get 7y=28/9 then divide by 7 to get y= 4/9
