Answer:
y=2/3x+2
Step-by-step explanation:
8x-12y=-24
subtract 8x from both sides to come up with -12y=-8x-24
divide -12y by everything and get y=-8/-12x-24/-12
simplify and get y=2/3x+2
its all positive since a negative divided by another negative= a positive
Well you could multiply both fractions by 2 (and get 6/8x4/6) and 3 (which would be 9/12x6/9) both of which would give you 1/2 just like 3/4x2/3 would. Or you could use 2/5x5/4 and 1/3x3/2 both which would also give you half :) hope this helps
