  • Hi i'm mr chad, and im going to solve this expression today
  • 10x - 30 ;x= -1
  • the first thing we need to do is substitute the -1 to any variable
  • 10(-1) - 30
  • next we change the subtraction into adding the opposite.
  • 10(-1) +30
  • next we multipy 10 and 1 which is 10
  • now we have to check for exponents their are no exponents in this expression so nothing changes
  • now we do the order of operations, the first thing we do is look for what's in the parenthesis, but theirs only -1 so we can't do anything yet
  • 10+30
  • next we subtract 10 from 30 and get 20
  • 20
  • 20 is the answer to the Expression!
  • 20!
