Sum would be 0 because the sum of additional inverses is always zero and the h would be on -1.4
Answer:
<h2>x = 19</h2>
Step-by-step explanation:
There are the vertical angles. The vertical angles are congruent. Therefore we have the equation:
<em>add 8 to both sides</em>
<em>subtract 6x from both sides</em>
I'm pretty sure you can just use a Cartesian plane and since all of your points are (positive, positive) they'd all be in the First Quadrant (top right)
So first, we want to substitute in 15 to all the x variables.
So,
3x - 8y = 5
Becomes
3 * 15 - 8y = 5
Or,
45 - 8y = 5
So here, you can subtract 45 from both sides to move all like terms to one side.
-8y = 5 - 45
And then simplify:
-8y = -40
Then divide both sides by -8
y = 5
