Answer:
Step-by-step explanation:
Y should still be 10 since x is 540
It's probably A because the fact that it is multiplied by 4 wouldn't change the number of zeros, and 10 to the 3rd power would be 1000 (if you include the X4 in this example it would be 4000).
There are no solutions to the equation.
Subtracting 3x from both sides gets you -12 = 1 which is never true therefore for any value of x you choose the equations will never equal each other
