Answer:
i think its 2 1
Step-by-step explanation:
Assuming you mean 2x-8y=7, we can start by multiplying the first equation by -2 and adding it to the second (to cross out the x), resulting in -18y=-5. After that, we can divide both sides by -18, resulting in y=5/18. Next, plugging that into 4x-2y=9, we have 4x-10/18=9. Adding 10/18 to both sides, we get 4x=9+10/18. After that, we can divide both sides by 4, resulting in x=(9+10/18)/4=
Answer:
False, there are actually infinite solutions as these are parallel lines.
Step-by-step explanation:
Answer:
you multiply both sides of the equation by x
you divide both sides of the equation by (2.5) to get x
