I think this is what you meant when posting your problem:
Firstly, we must rewrite this problem so it is easier to understand.
Step 1: Rewrite the problem without having to use powers


Step 2: Distribute the left side parenthesis


Step 3: Distribute the right side parenthesis

Step 4: Combine like terms


Step 4: Continue combining like terms

All of the terms cancel out, giving you 0
What you get: 0 = 4
This means that this equation is inconsistent, meaning that there are no solutions for this system.
0 cannot be equal to 4.
The answer is no solution.
