X = -3
Solution:
Distribute
6(x)+(6)(-1)+-x=-21
Combine
(6x+-x) + (-6) = -21
5x + -6 = -21
5x - 6 = -21
Add 6 to both sides
5x -6 + 6 = -21 +6
5x = -15
Divide both sides by 5
5x/5 = -15/5
x = -3
Answer:

(1/2 , 4)
Answer:
<h2><em><u>44</u></em><em><u>.</u></em><em><u>4</u></em></h2>
Step-by-step explanation:
<em><u>Let</u></em><em><u>,</u></em>
The number thought by Sushil = x
When halved = x/2
<em><u>We</u></em><em><u> </u></em><em><u>know</u></em><em><u> </u></em><em><u>that</u></em><em><u>, </u></em>
When the number is halved then it becomes 22.2
<em><u>Therefore</u></em><em><u>, </u></em>
The original number is,
=> x = 22.2 × 2
=> x =<em><u> 44.4 (Ans)</u></em>
