4x=2/3(x - 2)
4x=2/3x - 4/3 
 4x - 2/3x=4/3
 4x - 2/3x=-4/3 
10/3x=-4/3
x=-4/3 * 3/10 

x=-12/30 
x=- 2/5 
hope this helps

2/3(x - 2) = 4x....distribute thru the parenthesis
2/3x - 4/3 = 4x...subtract 2/3x from both sides
-4/3 = 4x - 2/3x
-4/3 = 12/3x - 2/3x
-4/3 = 10/3x
-4/3 * 3/10 = x
-12/30 = x
- 2/5 = x <==

distribute

2n = 59.2

divide each side by 2

n = 29.6

In a video game, Agnes scored 20% fewer than Amy. Amy scored 860
vovangra [49]

Answer:

\huge\boxed{\sf Agnes\ Score = 688\ points}

Step-by-step explanation:

\sf = 20 \% \ of \ 860 \\\\= \frac{20}{100} * 860\\\\= 2 * 86\\\\= 172 \ points

Since, Agnes scored 20 % fever than Amy.

So,

Agnes Score = Amy's Points - 20 % of Amy's Points

Agnes Score = 860 - 172

Agnes Score = 688 points

\rule[225]{225}{2}

Hope this helped!
