Well this question doesn't really make sense but I will answer anyway. If he drank 2L today then he drank 1,820ml yesterday.
X=3y+5 → x-3y=5 ..(1)
x-4y=3 ..(2)
→The second <span>equation we must multiplication by (-1)
→x-3y=5
→-x+4y=-3
x's is lost..
4y-3y=5-3
y=2
x-3.2=5
x=5+6=11</span>

1. Check all polynomials that are perfect square trinomials:9x2 − 6x + 1
16x2 + 24x + 9
2. Factor completely: x2 − 8x + 16
(x − 4)(x − 4)
3. Factor completely: 16x2 + 40x + 25
(4x + 5)(4x + 5)
