Answer:
s = 10500
Step-by-step explanation:
s/5 + 125 = 2225
Our mission is to isolate s. We can first begin to do this by subtracting 125 from both sides.
s/5 + 125 - 125 = 2225 - 125
s/5 = 2100
Since s is being divided by 5, we can multiply by 5 on both sides to get s alone.
s/5 x 5 = 2100 x 5
s = 10500

Answer:
x = -1 or 2
Step-by-step explanation:
Taking the antilog, you have the quadratic ...
x^2 -x -1 = 1
x^2 -x -2 = 0 . . . . subtract 1
(x -2)(x +1) = 0 . . . factor
The values of x that make these factors zero are the solutions to the equation.
x = 2 or x = -1
