Could someone check this equation for me please.I have added the steps I have done so far.
7x +9 = 5x5
subtract 5x from both sides and simplify
2x+9=5
subtract 9 from both sides
2x=4
divide by 2
x=2
Thought I had done it right but each side does not add up equally if x = 2.

7x +9 = 5x5
7x  5x = 9 + (5)
2x = 14
x = 7
Plug 7 in to see if it works.
I think you missed a minus sign in your work.
