To solve this equation, you need to isolate the variable on one side of the equation. Here's how you can do it:
Step 1: Add 7 to both sides of the equation to cancel out the -7 on the left side.
3x - 7 + 7 = 136 + 7
3x = 143
Step 2: Divide both sides of the equation by 3 to isolate the variable x.
3x/3 = 143/3
x = 47.67
So, the solution is x = 47.67 (rounded to two decimal places).

since the solution was not one of the choices, I suspect a typo.
How about
13x - 7 = 136
13x = 143
x = 11
How about
13x - 7 = 136
13x = 143
x = 11
Apologies for the mistake. You are correct.
Starting with the equation 13x - 7 = 136:
Step 1: Add 7 to both sides of the equation:
13x - 7 + 7 = 136 + 7
13x = 143
Step 2: Divide both sides of the equation by 13 to isolate the variable x:
13x/13 = 143/13
x = 11
Therefore, the correct solution is x = 11.
