Answer:
x = 0.5
Step-by-step explanation:
Well, we have in this case a exponent equation

Factoring 27 = 
Our new equation is:

Applying the property of exponents, on the right we'll have just like that:

now, it's easy to solve this equation. You must solve 3x = 2 - x because the basis of these exponents are equal.
3x = 2 - x
3x + x = 2
4x = 2
x = 1/2 or 0.5
Since they have the same denominator (4) which is the number on the bottom of the fraction, you can just add the numerators (3 and 4), which are on the top of the fraction, together:
3/4 + 4/4 = 7/4
Answer:

Step-by-step explanation:
Solve for x;
2x - ( x - 2 ) = 4x
distribute minus sign through parantheses
combine like terms
subtract x from both side
- x - x + 2 = 4x - x
- 2 = 3 x
Divide each side by 3
