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
