I need help with this please
Aleonysh [2.5K]

Answer:

x=5

Step-by-step explanation:

First, let's understand logarithms.

When there is no base given, like in this problem's right side of the equation, the base is automatically 10.

So, let's re-write that.

\frac{7}{x+2}=log_{10}x+5

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.

\frac{7}{5+2}  =log_{10}(5+5)\\\frac{7}{7} =  log_{10}(10)\\1 = 1
