Question

Find the value of x.

Answer 1

-2

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

x = -6

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!
