The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
Answer:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by −6 - 6 and simplify. Divide each term in −6y=12−2x - 6 y = 12 - 2 x by −6 - 6 .

Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:

-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:

-----------------------------------------
Number of chicken:
Since 






There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:

There are 16 pigs in the yard.
