keep trying to solve this one but canceling out x. i know x=-2 but i'm not quite sure how to get there in steps?

5^(2+3)-5^(x+2)=4

please help!

if I do the question exactly the way you typed it, we would get

5^5 - 5^(x+2) = 4
3125 - 4 = 5^(x+2)
log 3121 = (x+2)log 5
x+2 = log 3121/log5 = 4.999204
x = 2.999204
