Question

16=25+9x

Answer 1

I know the answer, but I cannot figure out how they got the answer... :/

Answer 2

what do you think the first step is?

Answer 3

Subtract 25. It would turn into a negative 25.

Answer 4

16=25+9x
16-25 = 9x
-9 = 9x
x= -1

Answer 5

Wait, no it wouldn't be negative, because minus signs mean lots of different things. :p

Answer 6

omistone seriously, you didnt even show all the steps

Answer 7

yes I did, what did I miss?

Answer 8

Well the first step

16 - 25 = 9x + 25 - 25
16 - 25 = 9x + 0
16 - 25 = 9x

The equality is maintained (both sides remain the same) because you did the same operation to both sides.
