Answer:
x=3
Explanation:
Because the base is the same for both sides the exponents have to equal each other. That means that we can make the exponents equal to each other and solve. This only works when the bases are the same, like how the bases here are both 9
2x+1=3x-2 --> 1=3x-2x-2 --> 1=x-2 --> 1+2=x --> x=3
