3x + 2 = 5x - 8
Flip
5x - 8 = 3x + 2
Subtract both sides by 3x
2x - 8 = 2
Add both sides by 8
2x = 10
Divide both sides by 2
x = 5
That's your answer.
Have an awesome day! :)

Hello.
24 points scored in 4 games = 24 * 4.
24 * 4 = 96
48 points scored in 10 games = 48 * 10
48 * 10 = 480
<em>96≠480, they are not equivalent.</em>
 
        
             
        
        
        
Step-by-step explanation:
Claim:  There's 14 Goats and 9 Chickens!!
Data:
 Working with the Provided Information.
Let the Number of goats be x 
let the Number of Chickens be y 
x + y = 23..... (i)
Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.
The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y
4x + 2y = 74 .....(ii)
BRINGING BOTH EQUATIONS TOGETHER.
x + y = 23
4x + 2y = 74
From Eqn i 
x= 23 - y 
Substitute into eqn ii 
4(23 - y ) + 2y = 74
92 - 4y + 2y = 74
92 - 2y = 74
2y = 92 - 74 
2y = 18
y= 9.
Substitute y into any of the eqns to get x 
x + y = 23
x + 9=23
x = 23 - 9 
x = 14
This simply proves that there are 14 Goats and 9 Chickens!!!.
HAVE A GREAT DAY!
 
        
             
        
        
        
I can't help without a question.
        
             
        
        
        
-2x + 12 = 2y
Add 2x on both sides,
12 = 2y + 2x
Divide by 2 on both sides,
6 = y + x -> x + y = 6
The answer is D.
