Question

How do I solve this exponential function using logarithms, it says if necessary you can round to the nearest hundredth, please show work!

Answer 1

The given equation is

`(x+7)=(2x-1)`

At first, we have to isolate x on one side and the numerical term on the other side, then

Add 1 to both sides

`\begin{gathered} x+7+1=2x-1+1 \\ x+8=2x \end{gathered}`

Subtract x from both sides

`\begin{gathered} x-x+8=2x-x \\ 8=x \end{gathered}`

The solution of the equation is x = 8
