Answer:
Step-by-step explanation:
Orginal equation:
So lets do this step by step.
First, lets add to both sides of the equation!
This gives us:
Then, when we put this into exponential form, we get:
This then equals:
This can be simplfied into:
Then we can add 32 to both sides, and subtract x from both sides to get the variable and number each on their owns ide:
Finally, we can divide 33 by 7 to get:
Hope this helps! :3
