Question

Find the value of x.

Answer 1

Answer:

-2

Step-by-step explanation:

The two angle are internal alternate relative to the two parallels, so they have the same measure.

$-8x+8 = -6x+20\\-2x=12 \rightarrow x = -2$

Answer 2

Answer:

x = -6

Step-by-step explanation:

The two angles given are alternate angles - this means they are equal. Therefore:

-8x + 8 = -6x + 20

We can solve this by first putting all the x's on one side and the numbers on the other side:

-8x + 6x = 20 - 8

Now we can simplify both sides down:

-2x = 12

Finally divide both sides by -2 to get x on its own:

x = -6

Hope this helps!
