1. y=7-3x
4x+2(7-3x)=16
4x+14-6x=16
-2x=2
x=-1
-3+y=7
y=10
(-1,10)
2. x=2y
2(2y)+2y=4
4y+2y=4
6y=4
y=2/3
x-2(2/3)=0
x-4/3=0
x=4/3
(4/3,2/3)

Simple Interest Formula: A = P(1 + rt)
1555 = 1000(1+(0.05*t))
1.55 = 1 + (0.05*t)
0.55 = 0.05t
11 = t
The answer is 11. Whether that is 11 years or months or whatever depends on your exact question.
It is in the simplest form
