To solve for x, we need to isolate it on one side of the equation.
Starting with the equation 2^x+3, we can subtract 3 from both sides to get:
2^x = -3
However, this equation has no real solutions because 2^x is always positive, while -3 is negative. So there is no value of x that would make 2^x+3 equal to -3.
I hope that helps! Let me know if you have any other questions.
