Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)

Answer:
x = -4
Step-by-step explanation:
<u>Step 1: Subtract 2x from both sides</u>
2x - 2 - 2x = 4x + 6 - 2x
<em>-2 = 2x + 6</em>
<em />
<u>Step 2: Subtract 6 from both sides</u>
-2 - 6 = 2x + 6 - 6
<em>-8 = 2x</em>
<em />
<u>Step 3: Divide both sides by 2</u>
-8 / 2 = 2x / 2
<em>-4 = x</em>
<em />
Answer: x = -4
