Answer:
B) -|x + 3| = 3
D) |x + 3| + 6 = 3
Step-by-step explanation:
A) |x + 3| = 3
B) -|x + 3| = 3
Divide by -1
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
C) |x + 3| + 3 = 3
Subtract 3 from each side
|x + 3| + 3-3 = 3-3
|x + 3| = 0
D) |x + 3| + 6 = 3
Subtract 6 from each side
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution

Answer:
(3,1) because x is 3 and y is 1.
Step-by-step explanation:
x+2y=5
3x+5y=14
Multiply first equation by 3:
3x+6y=15
3x+5y=14
Subtract 3x:
1y=1
Therefore, y = 1
Plug it back into 1st equation:
x+2(1)=5
x+2=5
Therefore, x = 3
Judging from your answers, it looks like (3,1) because x is 3 and y is 1.
