Solve for the unknown by using the additive inverse. Type the FULL answer in the box, without using any spaces (ex., X=5).

Answer:

X=16

Step-by-step explanation:

10x-8=9x+8

First you have to simplify.

10x-9x=1x

So now the equation looks like this

x-8=8

Now you have to get x by itself

-8+8=0 and we have to do the same thing on both sides of the equal sign 8+8=16

The equation now looks like this x=16

And that's your answer

Y = -2x - 5

lions [1.4K]

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

$y = -2\cdot x - 5$

$6\cdot x + 3\cdot y = -15$

$3\cdot y = -6\cdot x - 15$

$y = -2\cdot x - 5$

The second equation is identical to the first one, which means that there is just one line.
