I = $ 400
R = 5%
P =$ 2000
I = Prt
400 = 2000 * * t
400 = 20 * 5 * t
400 = 100 t
t = 4 years

<h3>Answer:</h3>
infinite solutions
<h3>Step-by-step explanation:</h3>Add the two equations.
... (-4x) + (y) = (y +3) +(-4x -3)
Add 4x -y to both sides.
... -4x +y +4x -y = -4x +y +4x -y
... 0 = 0 . . . . . true for all values of x (or y)
Both equations describe the same line.
