Answer:
Step-by-step explanation:
x > 3 reads x is greater than three. This includes all numbers to the right of three, but not three itself. |₋₋|₋₋|₋₋₀---|---|---|---|---|---|----->

<em>x =1/3</em>
- Step-by-step explanation:
<em>25ˣ⁺¹ = 125/5ˣ</em>
<em>5²⁽ˣ⁺¹⁾ = 5³/5ˣ</em>
<em>5²⁽ˣ⁺¹⁾ = 5³ : 5ˣ</em>
<em>5²⁽ˣ⁺¹⁾ = 5³⁻ˣ</em>
<em>2(x + 1) = 3 - x</em>
<em>2x + 2 = 3 - x</em>
<em>2x + x = 3 - 2</em>
<em>3x = 1</em>
<em>x = 1/3</em>
Let's call the numerator 
. Since the denominator is four more than three times the numerator, it means that it equals 
. So, the original fraction is
Note that this implies that 
, otherwise the denominator would be zero. Now, we need to increase both numerator and denominator by 4, obtaining this new fraction:
Note that this implies that 
, otherwise the denominator would be zero. And we know that this equals 925 (assuming that 925925 is some kind of typo/formatting error). This leads to the equation
Since we assumed that the denominator is not zero, we can multiply both sides by it, so that the equation becomes
Subtract 4 from both sides to get
Subtract 2775x from both sides to get
Finally, divide both sides by -2774 to get
