Short Answer

Expert verified

The solution of the given equation is-1.

Step by step solution

01

Step 1. Given Information

The given equation is3x+3=9.

We have to solve it.

02

Step 2. Solve the equation 

To solve the equation, write both sides of the equation with the same base.

So,3x+3=32.

Now, write a new equation by setting the exponents equal.

x+3=2x=2-3x=-1

03

Step 3. Verify the solution 

To verify the solution, substitute x=-1in the original equation.

3-1+3=932=99=9

Hence, our result is true.
