I think your supposed to add them all together or divide
Answer: Let's solve for x.
−x−y=6
Step 1: Add y to both sides.
−x−y+y=6+y
−x=y+6
Step 2: Divide both sides by -1.
−x
−1
=
y+6
−1
x=−y−6
Answer:
x=−y−6
Let's solve for x.
5x−7y=66
Step 1: Add 7y to both sides.
5x−7y+7y=66+7y
5x=7y+66
Step 2: Divide both sides by 5.
5x
5
=
7y+66

Step-by-step explanation:
I’m going to use Pythagorus theorem for his question. // firstly I would do 20^2 + 16^2 = 656 // we them square root that number, so the square root of 656 is 25.61, meaning the missing length is 25.6
X= -2
put x+3=-2x-3
+3. +3
x+6=-2x
-x. -x
6= -3x
/3. /3
x=-2
Answer:
x=83º
Step-by-step explanation:
The interior angle sum of a Hexagon is 720º
146+169+59+129+134+x=720
x=720-637
x=83
