Answer:
x= -2/9
Step-by-step explanation:
2(x-2)/5=4x
2(x-2)=4x*5
2(x-2)=20x
x-2=20x/2
x-2=10x
-2=10x-x
9x= -2
x= -2/9
For this case we have the following expression:

We multiply both sides by: 

We divide both sides by 216:

To divide powers of the same base, we place the same base and subtract the exponents:

Rewriting:

To multiply powers of the same base, we place the same base and add the exponents:

We know that any number raised to zero is 1, 
So, for equality to be true:

Answer:

Answer:
