Answer: See below
Step-by-step explanation:
a) 3x-6y=-12
x-2y=-8 --> x=-8+2y
3x-6y=-12
3(-8+2y)-6y=12
-12+6y-6y=-12
-24=-12
The statement is false for any value of y
b) If you solve the equations for y into slope-intercept form, they have the same slope
--> 3x-6y=-12
6y=12-3x
6 ÷ (6y=-12+3x) ÷ 6
y=1/2x+2
--> y=1/2x+2
x-2y=-8
-2y=-8-x
2 ÷ (2y=8+x) ÷ 2
y=1/2x+4
Since the slopes of the 2 lines are the same, they are parallel, and will never intersect
