Answer:
ummm Is that the full answer it's kinda confusing
y=-3x+4
x=2y+6
y + 3x =4
-2 + =6
x= 2y +6
y+3.(2y+6)=4
7y = -14
7y=-14
y=-2
y=-2
x=2y+6
x=2(-2)+6=2
solution is {y,x}= {-2,2}
120 days is approximately equals to 4 months. (30 days * 4 = 120 days)
Now you deposited 7000 dollars at 6.5% interests.
IN 1 months
=> 7000 * .065 = 455 dollars in 1 month is the interest
=> 455 * 4 months = 1820 dollars n 4 months
=> 7000 + <span>1820 = 8820 dollars.</span>
Awnser is in the photo below
