Answer:
no solutions
Step-by-step explanation:
3x - 6y= -12
x - 2y= -8
Solve the second equation for x
x-2y=-8
Add 2y to each side
x-2y+2y = -8+2y
x = -8+2y
Substitute this into the first equation every place to see x
3x-6y=-12
3(-8+2y) -6y=-12
Distribute the 3
-24 +6y -6y =-12
-24 = -12
Since this is never true there are no solutions.
60 mph means:
60 miles in 1 hour
×4 ×4
240 miles in 4 hours
You need to multiply both by the same number, so it is proportional.
