how would I solve for f(x)=g(x)? say we are given the equations f(x)= 3x-12 and g(x)=5x+20 what would I be solving? this is probably review from something I did years ago, but I cant remember​

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

How to do this , and can some one explain
