Question

can some 1 help me figure out this equation
2c-9=3c+9

Answer 1

what do we have to do ?

Answer 2

what letter are we working out?

Answer 3

realize that the = sign means that whatever you do to one side has to be done to the other to keep them equal...

Answer 4

2c-9=3c+9 ; lets -2c from both sides

2c-2c-9=3c-2c+9

-9 = c+9 ; now subtract 9 from both sides like this

-9-9 = c+9-9

-18 = c+0

-18 = c
