1. Move 2/x to the left side of proportion by changing sign before it:
3/x - 1 - 2/x = 4
2. Move 1 to the right side of proportion and change it's sign as well:
3/x - 2/x = 4 + 1
3. Sum numerators in the left side of proportion since they have common denominator (x) abd also sum the numbers in the right side too:
(3-2)/x = 5
4. Calculate numerator in the left side of proportion:
1/x = 5
5. Move 1 to the right side of proportion by dividing that side by it:
x = 1/5
18 is no solutions
24 is x=6
9x^3-6x^2+3x
Basically with this you just wanna simplify each term one-by-one.
For instance, look at the first term, 27x^4
Imagine 27x^4/3x
3 goes into 27 9 times, and x goes into x^4 4 times (cuz x to the power of 4 is just x times x times x times x)
So you’re left with 9x^3
