You can put this solution on YOUR website! 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.
