It's a logarithmic equation in one unknown.
If you'd like to know the value of 'x' that makes it true, you can find it like this:
15 log(2.5x) = 100
log(2.5x) = 100/15 = 20/3
log(2.5) + log(x) = 20/3
0.39794 + log(x) = 20/3
log(x) = 20/3 - 0.39794
x = 1020/3 / 100.39794
x = 1,856,635.533
=============================
Check:
log(2.5 x 1,856,635.533) = 20/3
15 (20/3) = 300/3 = 100 yay!
