9x-7=-7 
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.

Well, if we're looking for the value of "x" then follow these following steps! 

Our first step: 9(x) - [-7] = ?
 The "?" = 0 

Our second step 2: Solve this one → 9(x) = ? 
Remember that I said "?" equals to 0 

Our  third step: we have to divide by the number "9" on each of your sides

Our fifth step/your answer is:  [tex]x = 0[/tex] 

Oh and if you wanted to find out how many solution that it has, it would be One Solution 

There's not that much steps to this solution
