Does anyone know 2x=8y=7 4x-2y=9

1 answer:

5 0

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=

How do I factor 8x^2+12+48?

wolverine [178]

We can factor a 4 out of this expression.

4(2x^2 + 3x + 12)

Now that the expression is simplified, we can see if splitting the middle term is possible.

<em><u>Display factors of 24.</u></em>

1 * 24

-1 * - 24

2 * 12

-2 * -12

3 * 8

-3 * - 8

4 * 6

-4 * -6

All factors of 24 have been listed, and none of these digits satisfy the criteria.

Trinomial cannot be further factored.
