Answer: X=0
Step by step explanation:
3(x*2)=10*x      - use the commutative property to reorder the terms 
3*(2x)=10x   - remove unnecessary parentheses 
3*2x=10x      - calculate the product 
6x=10x      - move the variable to the left hand side and change its sign 
6x-10x=0    - collect like terms 
-4x=0        - divide both sides of the equation by -4 
X=0
